button to select any date range for your data display.
The License info tab shows information about your license, contact person, as well as the extensions enabled on your TrueConf Server instance. Here you can also renew your TrueConf Server license using the Register button, or purchase additional features in the Extensions section:
In case of any problems with TrueConf Server registration, the administrator may reach out to TrueConf technical support team via the contacts that will be displayed in case of an error.
If you're using a free version of TrueConf Server and connection to our registration server (host is reg.trueconf.com and TCP port is 4310) is lost, your server will shut down in 12 hours. The expected shut down time will be displayed in the Summary tab. The full version of TrueConf Server does not impose such limitations.
If the server is connected to the Internet, administrator will be able to receive notifications updates in TrueConf Server control panel. In the left menu of the control panel you will see a notification, while at the top of the page a message with the latest version download link will be displayed. After you have updates, the notification will disappear.
# Settings
In this section you can specify the path where TrueConf Server data will be saved. Here, it is also possible to view detailed analytics about the server performance and configure settings for client applications.
- A path to a working directory of server.
The working directory path /opt/trueconf/server/var/lib cannot be edited in the TrueConf Server for Linux control panel. We recommend using symbolic links ("symlink") if you want to do it.
2. Enable detailed logging of your TrueConf Server activities. Might be required by our technical support team for troubleshooting.
You can read more about TrueConf Server log files and learn which logs are required for troubleshooting and reporting tickets to the technical support department in our knowledge base.
3. Backup and restore TrueConf Server settings (learn more below).
4. Go to the version settings for TrueConf for Windows client application.
5. Download link for TrueConf for Windows client application (the link will be published for your users on the guest page).
6. A field for generating a secret key. It is used for creating session keys to authenticate users in a video conference. To replace your key with a new one, click the Generate a new key button. By replacing the key you can make your conference more secure (e.g. inhibit third-party connections).
7. A key similar to the previous one. It controls authorizing using guest accounts in public conferences.
8. Setting the maximum default bitrate that can be sent from each client application to the server.
9. Set maximum FPS rate transmitted from TrueConf Server to a client.
10. Set frame size limits in pixels.
11. Enable statuses (icons used as reactions) during a conference.
12. Save application settings.
We strongly advise you not to use settings 6-10, unless being told so by our technical support team, as they might significantly decrease the quality of your video conferences or put TrueConf Server security at risk. The ability of TrueConf Server to automatically and dynamically manage video streams encoding parameters is crucial for effective collaboration.
# Configuration back-up and restore
Backup copy of TrueConf Server settings will enable you to save the main server settings, including users, groups, scheduled conferences, network settings and then restore the server settings from the file where the settings were saved. This feature may be helpful when the operating system is re-installed or when the server is migrated to a different physical machine. You will not have to configure the server once again. Check full guides in our knowledge base to learn more about saving and restoring settings:
- TrueConf Server migration from one Windows server to another
- TrueConf Server migration from one Linux server to another
- TrueConf Server migration from Windows to Linux
- TrueConf Server migration from Linux to Windows.
When TrueConf Server settings are saved to a file, the reserve copy of this file will be automatically created in the [working_path]\registry_backups folder where [working_path] is the working directory of a server. This applies both for Windows and Linux versions of TrueConf Server.
# Client application version settings
Below you can see the client application section. Here you can put limitations on the versions of the applications which can be used for video calls and conferences on your TrueConf Server instance.
Click on the client application in the first table row:
Here, you can edit the following parameters:
Minimal version of the client application supported by TrueConf Server. If the current version of client application is lower that the one specified here, client application will be stopped and mandatory updated.
Preferred version of the client application. If the version of the app is older than the version specified in this field, the user will be prompted to update. It's possible to cancel the update and continue to use the application unless it's version is higher then the Minimal one.
The version of client application which will be offered for update.
# Network
In this section you can adjust some network settings for your TrueConf Server instance:
connecting client applications and third-party devices (SIP, H.323, etc.)
sending email notifications for users and administrator
connecting to other TrueConf Server instances.
# Network Settings
In this section you can specify IP addresses and ports which will be used by TrueConf client applications to connect to TrueConf Server. IP address of the computer where TrueConf Server is installed is used by default.
Client applications always connect to TrueConf Server over the only TCP port (4307is used by default). It is the only port used for signalling, sending authentification data and audio or video streams. An HTTPS port (443 selected by default) is used for displaying the scheduler, accessing real-time meeting management and for API calls. To learn more about this topic, check out the article in our knowledge base.
You can specify a different port when editing the list of IP addresses.
No UDP port can be used for communication between TrueConf Server and a client application.
The Internal addresses list includes the addresses and ports that the server listens for incoming connections from client applications. These are the addresses of network interfaces on the computer where TrueConf Server is installed. It can also be the internal DNS name of this computer; this name will be resolved to one of the network interfaces by IP. If the Listen on all IP addresses box is checked (it is checked by default), the list is automatically compiled; it will include all such addresses including virtual ones.
To edit the Internal addresses list, you will need to:
Uncheck the Listen on all IP addresses box.
To change the parameters for the specific connection, just click on the line with the selected address.
Use the buttons at the end of the list to add a new address and to save or discard changes.
The addresses from the External addresses list will be encrypted and embedded into the name of TrueConf for Windows installer. These addresses will be used when the application is started for the first time. Client applications downloaded from your TrueConf Server instance will try to connect to these addresses on a first-priority basis (if these addresses are unavailable, the application will try to connect to internal addresses). So, you should include the addresses that will be available to the users both inside and outside the corporate network. This list may include the addresses forwarding to internal addresses, IP address of your NAT, DNS name or the addresses where you are planning to migrate TrueConf Server (this is usually done so that the applications that were downloaded previously could connect to the server via a new IP address). If the server is designed to operate in LAN only, you don't need to use this list.
To edit the External addresses list, mark the Specify checkbox.
If you plan to migrate the server to another IP address, all you need to do is to add the new IP address to the External addresses list beforehand. This will help client apps to store the new address right after the next connection to the server in advance.
When the external address is adopted, go to the Web → Settings section section in the control panel and change the external address of the web page to a public IP (indicated in the External addresses list). Then restart the server so that external users can connect to it from outside.
This guide does not cover TCP port forwarding or DNS names. You can learn more about these topics in your network equipment manuals.
# SMTP
Although TrueConf Server doesn't have a built-in mail server, it can use an external SMTP server or service to deliver email notifications, invitations and other important messages to your users. You can change the templates used for these messages in this section as well.
To configure an SMTP connection:
Specify the host (the address of the mail server).
Select a secure connection type: SSL, STARTTLS, or none.
Specify the port for your connection type if it is not default.
Select authentication mode (simple password or no authorization). If you have chosen password-protected authentication mode, please enter login and password to connect your TrueConf Server instance to the SMTP server.
Fill in the email address fields (full mailbox address, including login, @ and domain) and sender's name in the SMTP From field. In this case, the address should match the login and host specified above.
Check your settings using the Check connection button. The current status of your connection to the mail server is displayed in the Status: field: successfully connected in case of successful connection to the SMTP server and invalid server if the connection can not be established.
Enter your TrueConf Server administrator email to be displayed in the outgoing emails. Enable the checkbox below the input field so that the administrator is notified when TrueConf Server restarts due to internal errors.
Click Apply at the bottom of the page to save changes.
You can configure email templates to notify registered and unregistered users about missed calls or invite them to scheduled meetings. The corresponding templates can be found below the SMTP server connection settings.
To receive missed call notifications, enable the Notify users about missed calls checkbox. If any of the users is offline during the call or conference invitation, TrueConf Server will send an email notification at the email address specified in the E-mail field in the user account settings or in the corresponding field imported via LDAP synchronization.
To enable email invitations for all new scheduled conferences, enable the Send invitations to participants of the group conference checkbox. In this case, when scheduling a meeting, all invited users will receive email invitations where date and time of the meeting (if any) is specified.
To send confirmations of a successful webinar registration (available if corresponding settings have been adjusted), use the Conference registration notification template.
To notify users when they are removed from the list of invited participants, mark the Notify users if they are removed from the participant list checkbox. These settings will be applied to all conference modes. If registration settings have been configured for the webinar, the notification will be received by the participants who signed up for the webinar and those users who were invited to the list of participants when the conference was created.
You can enable or disable email invitations for each meeting individually in the Advanced tab when creating or editing the conference.
# Parameters used in email templates
Use the following syntactic structures to customize the templates of emails sent by TrueConf Server:
For notifying users about missed calls:
%caller_display_name— display name of the caller%сaller_call_id— ID of the user who made the call (e.g.user@server.trueconf.name)%recipient_display_name— display name of the caller (the user who missed the call)%missed_call_time— time and date of the call.
additional variables for missed call notifications sent to unregistered users:
%recipient_call_id` is the ID of a user who missed the call.
“%tcs_guest_page_url” is the guest page URL of your TrueConf Server.
For inviting to a conference:
%conf_name— name of the conference%conf_id— ID of the conference, e.g.\c\df0a2adebe%owner_name— display name of the conference owner%user_display_name— display name of the user who is invited to the conference%start_timeis the time and date of the conference start. The time corresponds to the server time zone which will be specified in the email. Participants should take into account time zone differences to join the conference at the correct time.%conf_description— conference description specified in the Advanced → Description section when the conference is being created.%conf_url— the link to the conference page, e.g.,https://server.trueconf.name/c/CID.
For notifications about webinar registration:
%conf_unique_link— the unique conference link provided to each participant.
Server administrator contacts parameters:
%admin_name— display name%admin_email— email address%admin_phone— phone number.
# Federation
With federation mode, your users can call and invite to conferences users of other TrueConf Server instances. Federation is available only in the TrueConf Server standard version (i.e. for every paid license). The number of federated servers is unlimited. The maximum number of participants in a group video conference is limited to the license of the TrueConf Server instance initiating the meeting.
The federation has to be configured for both servers so that they could be accessible to each other according to the rules specified below. To configure federation, you will need to:
In the drop-down list, select the federation mode:
- Disabled
Allowed for whitelisted servers. In this mode, only TrueConf Server instances specified in the whitelist can be federated
Allowed for all but blacklisted servers. In this mode, all TrueConf Server instances can be federated except for those specified in the blacklist.
2. Enter the IP addresses or domain names (FQDNs) of the required servers into one of the lists (depending on the federation mode) and click Add.
It is not necessary to specify IP addresses; only DNS (FQDN) names are needed.
3. To configure federation with TrueConf Online cloud service, please make sure that the outbound 4308 port is open. For more information about the outbound ports used in our solutions, take a look at the table in the corresponding article from our knowledge base.
4. Click Apply to restart your TrueConf Server instance and save the changes.
To be able to operate in federation, your TrueConf Server instance should be available to other servers and client applications by its DNS (FQDN) name indicated during the registration process. The server should be registered either under an existing DNS name or a server address using SRV DNS records.
If you would like to learn more, proceed to the client application automatic settings section.
Let us take a look at some examples.
Case 1
By adding trueconf.com to the whitelist, you can allow your server users to call and receive calls from TrueConf Online cloud video conferencing service users (only those whose TrueConf ID has the following format: id@trueconf.com). The federation on the side of TrueConf Online has been configured with an empty black list. So, the users of the cloud video conferencing server can receive calls from any TrueConf Server instance.
Case 2
To configure federation with a different TrueConf Server instance, e.g., videoserver.company.com, you will need to:
Add
videoserver.company.comto the white listActivate federation on the side of
videoserver.company.comin one of the following ways:Add the domain name of your server to the its white list
Allow federation with all the servers that have not been added to the black list (make sure that your server is not added to the black list).
3. Make sure that both servers and TrueConf client applications connected to these servers are accessible to each other via their domain names.
Case 3
If the videoserver.company.com server was added to the black list, the users from your server and all the users with id@videoserver.company.com ID will not be able to make calls to each other.
Connection to a conference in federation mode
Connection to a conference (including the cases when federation is used) is fully described in the "Conference page" section.
# Gateways
TrueConf Server has a built-in gateway for SIP 2.0, H.323, and RTSP protocols interoperability.
If you would like to learn more about SIP/H.323 integration use cases, read our articles:
- How to set up telephony: TrueConf Server and Asterisk integration
- How to integrate TrueConf Server and Cisco Unified Communication Manager via SIP
- How to register TrueConf Server on the external H.323 Gatekeeper
Built-in gateway is necessary only if you need to call the devices connected to a third-party server (e.g. H.323 gatekeeper, PBX, MCU). Otherwise you can use the call string for SIP 2.0/H.323 devices.
TrueConf Server can process tone dialing signals; so, you will be able to send the following DTMF commands from your SIP/H.323 endpoint in “smart meeting” mode:
1– request to take the podium.2– to leave the podium.
To do this, use the supplied remote control or keypad. For more details, read the manuals for your specific device.
In our knowledge base, we discussed the use of Polycom HDX series endpoints together with TrueConf Server, including sending DTMF commands from them.
# Sip gateway
This section helps to configure TrueConf Server built-in SIP 2.0 gateway parameters. The number of rules created using these settings is unlimited.
TrueConf Server Free version provides only one active connection through the gateway, including SIP 2.0, H.323 and RTSP protocols.
Calling up devices via SIP gateway requires specific call string formats.
# Network settings
This list contains the addresses that are used by the gateway to listen for incoming SIP 2.0 connections. By default the list is prefilled with IP addresses provided by your operating system. You can edit this list by unchecking Listen on all IP addresses checkbox.
# Rules for SIP connections
In this section you can create specific rules for certain SIP addresses or call directions. For example, you can use special set of settings to connect to Skype for bussiness servers and another one for PBX connectivity. Every rule is relevant only for target address specified in Host field. Every rule redefines global settings for SIP 2.0 connections.
Gateway can also authenticate on and maintain active connection with SIP devices for which the rules have been created. This option can be useful to maintain permanent connection with PBX or VoIP services. You can find the connection status in the rules for SIP Connections table.
To create a new rule, click Add a configuration and select one of the two possible templates: manual configuration or Skype for bussiness connection. Skype for bussiness template has some preselected features required for Skype for bussiness interoperability, e.g. port, protocol, used video codec and registration mode.
# New rule form
Name field is only displayed in the table for rules. Host and Port fields are more important and also mandatory. They are required to determine call direction applied to this rule. If you are using an SIP proxy server, enter its IP address or domain name in the corresponding field. If the port for connecting to the proxy is different from the 5060 default port, enter the required port after the address and separate it with a colon. Please note that it isn't possible to set different rules for one host but different ports.
In the External NAT IP address, you can specify the IP address or domain name of the server which will be set in SDP for receiving and sending media streams when calling users outside NAT.
The following block of fields is designed to authorize on an SIP device for which the rule is created. If the Authorization name is the same as login, you may leave this field blank. You can use International call prefix to replace the '+' symbol used in phone numbers with another value, e.g. '810'. If you leave this field blank, '+' symbol will not be replaced in the phone numbers your users are calling to.
Registration mode defines registration method for the rule:
off — REGISTER request is not sent, registration or authorization on the external SIP device is not performed.
permanent — registration is performed automatically when TrueConf Server starts.
before call — registration is performed before every call and is kept active only during the call.
You can manually specify the connection protocol (TCP, UDP or TLS) if necessary.
Please note that each active gateway connection reserves one SIP 2.0/H.323 connection from TrueConf Server license.
If you want to reduce SIP packets and headers and prevent potential issues that can be caused by exceeding maximum allowed packet size (MTU), you can use options in the Reduce SIP messages size block.
Enable ICE support (Interactive Connectivity Establishment) checkbox makes TrueConf Server gateway available behind NAT.
Enable SRTP support checkbox is used to encrypt media data sent in this direction. For some SIP devices encryption is mandatory (e.g. for Skype for bussiness servers).
Enable content sharing via BFCP checkbox will allow you to send and receive content from SIP devices as a second video stream. For example, it can be used to share desktop from the PC connected to SIP endpoint, or send slides back from TrueConf applications to SIP endpoints.
When you share content as a second stream from your SIP or H.323 device, the content is transmitted with a reduced frame rate to save traffic. If you need to transmit the second stream content at a higher frame rate, please contact our technical support to switch to the appropriate mode.
Enable far end camera control via Q.922/H.224/H.281 checkbox enables support for far end camera control of SIP endpoints from TrueConf client applications.
Please note that this parameter has the same name in the SIP and H.323 gateway configuration menus, however, these are two different checkboxes responsible for different permissions.
Enable timers support (RFC4028) is used for disconnecting SIP endpoint from the conference when the connection is lost.
You can manually specify Max session refresh interval (seconds) (1800 seconds by default).
The list of Available codecs displays the codecs which gateway is allowed to use in this direction. Disabling some of the codecs can solve compatibility issues with certain SIP devices, eg. Lifesize endpoints. For more details please contact our technical support team.
SIP device for which the rule is created can take special roles:
Default SIP trunk. This role allows users to avoid entering full SIP URI for calls with
#sip:prefix. For example, all calls in the#sip:Endpointformat will be automatically replaced with#sip:Endpoint@Host, whereHostis taken from the properties of this rule andEndpointis a username specified during the call.Default VoIP server. This role is required for treating an SIP device as a VoIP server or a PBX and activating the dialers built in TrueConf client applications. All the calls made from application dialers or with the help of
#tel:prefix will be automatically forwarded to this SIP endpoint. For example,#tel:Phonewill be automatically replaced with#sip:Phone@Host, whereHostparameter is automatically taken from the properties of this rule andPhoneis replaced with the phone number entered by user.
Please note that each of these roles can be assigned only for one SIP 2.0/H.323 connection rule.
# Skype for Business integration configuration
This integration is designed to work with Skype for bussiness 2015 Server or Lync 2013 Server on-premises deployments and cannot be used for their cloud versions.
To connect successfully, you will need to receive a trusted root certificate from the Skype for bussiness administrator and install it in the system where TrueConf Server is installed.
Create a new account on Skype for bussiness server for TrueConf Server gateway.
Use Skype for bussiness template to create a new rule for SIP connections. Enter username and password of this freshly created account in the appropriate fields.
Enter Skype for bussiness server IP address or domain name in the Host field.
Check Default SIP proxy checkbox.
Save the rule and check if the connection status has changed to successful in the table for rules. Please note that TrueConf Server service must be running.
To call Skype for bussiness users from TrueConf client applications, use the following format: #sip:User, where User is TrueConf username. This user will receive an incoming call from the TrueConf Server account. The same method is used to invite Skype for bussiness users into the conference or add them to address book.
To call TrueConf users from Skype for bussiness client application, send the following message to the user created for TrueConf Server authentication: /call <TrueConf_ID>, where <TrueConf_ID> is any valid TrueConf Server user ID including SIP / H.323 devices registered on TrueConf Server. You can use /conf command to create a multipoint conference, etc. After the message has been sent, TrueConf Server will Skype for bussiness user and connect him/her to a TrueConf user or a conference. If you try to call this user directly, the call will be rejected and you will receive a help message with a list of available commands in chat. However, if default call destination is set in global SIP settings, you will be connected to this default destination address.
Please note that you can also create a group conference on TrueConf Server and invite into the conference the endpoints connected via any protocols the gateway supports. For example Skype for bussiness users and various SIP/H.323 devices or RTSP IP cameras.
# Global SIP settings section
Settings in this section automatically apply for all SIP 2.0 connections for which there are no rules.
Default call destination. When calling any address listed in the Network settings via SIP 2.0 protocol, all calls will be forwarded to this user ID or conference ID (CID).
SIP From domain. It is used to generate a SIP URI for outgoing calls in the following format
user@server, whereserveris the IP address or FQDN value anduseris the user ID who initiated the call. It is usually displayed as a caller address on SIP devices.
Other settings are similar to those used to create connection rules.
# Invitation of the SIP endpoint to the conference on TrueConf Server
There are multiple ways of inviting a SIP endpoint into a conference: conference owner can call a SIP endpoint using a specifically formatted call strings from TrueConf client application. Alternatively, administrator can do it from TrueConf Server control panel.
To add an SIP endpoint to the conference via control panel you need to:
Select a conference in Group conferences list.
Add SIP endpoint as a participant of the conference if it's not started yet, or invite in case it's already running. Use a call string to address the SIP endpoint.
# How to join a conference with its CID (conference ID) from an SIP endpoint
To connect to a conference from the endpoint registered on TrueConf Server, enter CID (Conference ID) into the endpoint address field. Please note that you need to replace \c\ in CID with 00 (two zeroes) when calling from external endpoints. In our case, you need to enter 00e22a39ba2a@<server> if CID is equal to \c\e22a39ba2a.
To connect to the conference from the endpoint unregistered on TrueConf Server, use the following format:
CID@<server>:<port>
where:
CIDis a conference ID with two leading zeroes instead\c<server>is an IP address of TrueConf Server gateway e.g.,00e22a39ba2a@192.168.1.99<port>— connection port (in case it is different from the standard 5060 port).
Additionally, in the case of SIP it is possible to specify the protocol name explicitly (UDP is used by default):
CID@<server>:<port>;transport=<protocol>
For example, 00e22a39ba2a@192.168.1.99:5061;transport=TCP.
You can also find an instruction on how to connect to a conference held on TrueConf Server from an SIP endpoint on the conference web page.
# H.323 gateway
This section explains how to configure built-in gateway parameters for H.323 connections. The number of rules for H.323 connections created using this section of control panel is unlimited.
TrueConf Server Free version provides only one active connection through the gateway, including SIP, H.323 and RTSP protocols.
H.323 connections are generally used to call third-party video conferencing endpoints. With TrueConf Server you can also set up H.323 integration with MCU, H.323 gatekeeper and PBX, which can be useful for addressing endpoints and users registered on these devices via H323-ID or E.164 without specifying IP address of the endpoint in the call string. To call an endpoint via H.323 gateway, there is a special call string format.
# Network settings
This section includes the list of addresses listened by the gateway for incoming H.323 connections. By default the list is prefilled with IP addresses provided by your operating system. You can edit this list by unchecking Listen on all IP addresses checkbox. The list of ports used for H.323 connections is available in our blog.
# Rules for H.323 connections
Here you can create specific rules for certain H.323 devices or call directions. Each rule is relevant only for specific destination address indicated in the Host field and redefines global settings for H.323 connections.
The gateway can also register on H.323 devices and maintain an active connection, which might be useful when connecting to an MCU or H.323 gatekeeper. The status for such connection is displayed in the rules table. To create a new rule, click Add a configuration button.
# New rule form
Name field value is used only to distinguish one rule from another. Host and Port fields are also mandatory. They are required to determine call direction to which this rule will be applied. Please note that it isn't possible to create different rules for one host but for different ports on it.
In the External NAT IP address, you can specify the IP address or domain name of the server which will be set in SDP for receiving and sending media streams when calling users outside NAT.
H323-ID and Password fields can be provided to authorize on H.323 device for which the rule is created. To maintain permanent connection with this device, you’ll need to select necessary item in the Registration drop-down list.
Once successfully registered on the H.323 device, TrueConf Server can be reached via phone number in the E.164 format provided it has been specified in the DialedDigit field. This setting can be useful if bundled with Default call destination option in the global H.323 settings section. In this case all calls to the specified DialedDigit number outcoming from the connected H.323 device will be redirected to a specific user ID or conference ID on TrueConf Server side.
Please note that each active gateway connection reserves one SIP/H.323 connection from TrueConf Server license.
Enable H.235 encryption checkbox enables encryption of the media streams sent to H.323 devices according to ITU-T H.235 version 3 recommendations. It is required for proper interoperability with some endpoints.
Enable content sharing via H.239 checkbox allows to send and receive content from H.323 devices as an additional video stream. For example, it can be used to share desktop from the PC connected to H.323 endpoint or to send content from TrueConf applications in the opposite direction.
When you share content as a second stream from your SIP or H.323 device, the content is transmitted with a reduced frame rate to save traffic. If you need to transmit the second stream content at a higher frame rate, please contact our technical support to switch to the appropriate mode.
Enable far end camera control via Q.922/H.224/H.281 checkbox enables support for far end camera control of H.323 endpoints via **Q.922, H.224 and H.281** protocols from TrueConf client applications.
Please note that this parameter has the same name in the SIP and H.323 gateway configuration menus, however, these are two different checkboxes responsible for different permissions.
The list of Available codecs displays the codecs which gateway is allowed to use in this direction. Disabling some of the codecs can solve compatibility issues with certain H.323 devices.
H.323 device for which the rule is created can take special roles:
Default H.323 gatekeeper. This role allows users to avoid entering full address of the H.323 device using
#h323:prefix. For example, all calls in any direction in the#h323:Endpointformat will be automatically replaced with#h323:Endpoint@Host, whereHostis taken from the properties of this rule andEndpointis a username specified during the call.Default VoIP server. This role is required for treating an H.323 device as a VoIP server or a PBX and activating the dialers built in TrueConf client applications. All the calls made from application dialers or with the help of
#tel:prefix will be automatically directed to this H.323 endpoint. For example,#tel:Phonewill be automatically replaced with#h323:Phone@Host, whereHostparameter is automatically taken from the properties of this rule andPhoneis replaced with the phone number entered by user.
Please note that each of these roles can be assigned only for one H.323 rule.
# Global H.323 settings
Most of the settings in this section are identical to the settings described above. However, they automatically apply for all H.323 connections for which there are no rules.
Use Default call destination field to enter TrueConf ID or conference ID (CID) which will receive all incoming calls over H.323 protocol in cases where destination user ID wasn't specified.
# How to call TrueConf users and conferences from H.323 devices
Depending on the H.323 endpoint model there are two different methods to call TrueConf Server users and conferences: using SIP URI or hashes (##) notation. Please try both to find the one suitable for your H.323 equipment. The call strings provided below should be entered as a string or number to call in the endpoint’s interface. TrueConf Server IP address mentioned below could be an any address specified in H.323 network settings section:
Server##User, whereServeris TrueConf Server IP address andUseris ID of the user or device registered on TrueConf ServerServer##00CID, whereServeris the IP address of TrueConf Server whileCIDis the ID of a conference hosted on TrueConf ServerUser@Server, whereUseris ID of the user or device registered on TrueConf Server andServeris TrueConf Server IP address\c\CID@Server, whereCIDis ID of the conference on TrueConf Server andServeris TrueConf Server IP address00CID@Server, where first two characters are zeroes,CIDis ID of the conference on TrueConf Server andServeris TrueConf Server IP address.
Call formats for H.323 and their examples are fully described in the user guide.
# How to register H.323 devices on TrueConf Server
TrueConf Server can act as a gatekeeper or MCU for third-party H.323 devices and simplify their addressing. From the TrueConf Server user perspective an H.323 device registered on the server does not differ from any other user: you can see its status, call it from the address book or invite to the conference without using call strings notation. Similarly, calls using H323-ID names from a registered H.323 device interface will be interpreted by the server as a call to specific TrueConf ID to entered H323-ID.
Registering an H.323 device on TrueConf Server is similar for most endpoints available on the market. Basically, to do so, you will need to specify TrueConf Server address as a gatekeeper or MCU address and use username and password of any TrueConf Server account to authenticate.
# RTP
In the Gateways → RTP section, you can configure the UDP port range used to exchange media data for SIP/H.323 calls (50000-51999 by default).
# WebRTC
In this subsection you can configure the UDP port range for a WebRTC connection (53000-55000 by default).
You can also specify the address used for NAT traversal if automatic detection fails for some reason in the Public IP address is added to SDP as an extra ICE candidate field in the TrueConf Server control panel.
# Transcoding
This section enables you to set up video conferencing quality for WebRTC users (in browsers), H.323/SIP/RTSP devices and recording fixation.
Cheking the box Do not display self-view in video layout for H.323 and SIP endpoints allows displaying the conference layout for SIP and H.323 devices without the self-view window. In other words, an individual layout will be created for an SIP/H.323 participant with no video from the camera connected to the endpoint.
This setting can significantly increase the load on the CPU of the physical machine with TrueConf Server installed.
When the box Use GPU to reduce CPU load is checked, video conferences will be processed by the GPU of the physical machine with TrueConf Server installed.
# Web
In this section, you can find settings for your guest page and control panel access.
# Web Settings
To change the guest page URL and its appearance, you can use the following options:
The TrueConf Server address which is used to generate links to the server guest page and conference pages. Make sure that it is available to all users of your TrueConf Server instance. In case of an unstandardized port (different from HTTP
80or HTTPS443), type it with a colon in the address field, e.g.,https://video.server.com:4433. Besides, if HTTPS is used, make sure to specify this protocol in the server address.A link to the guest page which contains instructions on how to connect new users to TrueConf Server.
Your company's name which will be displayed on the guest page.

# Security
In this section you can set up access to your TrueConf Server control panel and TrueConf Server API.
Read more about TrueConf Server admin roles on different operating systems in the TrueConf Server installation and initial setup section.
Select the users of your operating system who will be granted access to your TrueConf Server control panel.
If this option is enabled (it is enabled by default), the control panel can be accessed without authorization from the computer on which your TrueConf Server instance is installed (browser’s host is
localhostor127.0.0.1). Uncheck the box if you require all admins to authorize.
Please make sure that you have a user account that is a member of TrueConf Server Admin group (for Windows) and tcadmins (for Linux) on the computer where your TrueConf Server instance is installed. Otherwise, you will not be able to authorize and access the TrueConf Server control panel after you’ve saved the changes. If you’ve still faced this issue, please reinstall TrueConf Server or contact our technical support department.
3. Check this box to make sure that your server is available for control only to the IP addresses specified in the list. In such a case the Administrator login button will be displayed only if the guest page is opened from the IP address added to this list. If the guest page is opened from the IP address which is not included in the specified ranges, the button for administrator login will be hidden.
4. Press this button to add a subnetwork with access to the control panel. Add the address in the Network address field (admissible symbols are numbers and dots, admissible format is 4 octets in decimal representation without initial noughts from 0 to 255, separated by dots, e.g. 192.168.11.10). To open a drop-down list in Subnet mask field click the arrow on the right side and choose the appropriate option. 32 - 255.255.255.255 mask is set by default.
5. Secret security key for accessing API of your TrueConf Server.
With a secret key, you can access APIs with no time limits or verifications until the key is changed. This is why we recommend that you use the secret key only for testing purposes or for TrueConf Server admin with privileges that cannot be specified when creating an OAuth application (e.g., viewing logs). For regular operation, please use OAuth2 technology.
6. Click to generate a new secret key. Reverting to the previous key or using your own is not possible.
7. Click to apply the changes.
# HTTPS
In this control panel section you can configure the safety data transfer parameters between your browser and TrueConf Server.
A secure connection with your TrueConf Server instance is necessary for capturing media devices using WebRTC technology in all modern browsers. Thus, users won’t be able to join your meeting from their browsers if you haven’t enabled HTTPS connection.
HTTPS is also required for users connected to your TrueConf Server instance from their client applications. Without it, they won’t be able to access and use conference scheduler, show slides and manage meetings in real time.
TrueConf strongly recommends that you should configure HTTPS even if you are not intending to use TrueConf Server for holding public conferences and connecting participants via a browser (via WebRTC). Using HTTPS is one of the best practices for web services and helps to enhance the security of video communication.
After configuring HTTPS, you need to update the external address of your server in the Web → Settings section and make sure that it starts with https. For example: https://video.company.com.
# HTTPS configuration
In this section you can select your certificate and set other HTTPS parameters. The web server applies HTTPS settings at startup. If invalid certificate port and parameters are entered, the web server will not start and administrator will lose access to the control panel. Therefore it is required to carefully check the parameters beforehand.
Select one of the three operating modes in the HTTPS mode dropdown list:
Disable HTTPS. HTTPS protocol will not be used.
Use self-signed certificate. This mode uses a certificate automatically obtained from the server (this certificate is not suitable for connecting external users via WebRTC).
Use custom certificate. This mode uses a certificate uploaded by the TrueConf Server administrator.
2. Specify the TCP port that the web server will use for HTTPS connections (use numbers) in the HTTPS port: port field. Port 443 is set by default.
Set the versions of the TLS protocol that your TrueConf Server instance will use for HTTPS operation.
4. Click the Test configuration button to verify the HTTPS configuration data without restarting the web server. This action does not change the configuration file of the web server.
5. Click Apply to save the web server configuration file with the specified parameters. You will see a dialog box notifying you that this action will automatically lead to your TrueConf Server instance restart.
# Self-signed and custom certificates
There are two certificate types available in TrueConf Server. If you are using a trusted certificate, no additional actions are required, as browsers trust certificate authorities who signed it. To configure an uploaded certificate, the server administrator requires an X.509 certificate and the correct private key.
As an alternative you can also use a self-signed certificate:
a self-signed certificate is valid for 365 days and can be generated from control panel
this certificate can be renewed for unlimited period of time
with a self-signed certificate, you can test WebRTC without purchasing a trusted certificate
# Self-signed certificate
If you have previously created a self-signed certificate, here you can find the basic parameters of the root certificate, Create a new SSL certificate button, as well as the certificate to be used by the web server and TrueConf Server:
To create a new self-signed certificate, press Create a new SSL certificate. You may use this option to renew your certificate for 365 days or to update information about your company in the certificate (if your company’s name has changed). Administrator can download a root certificate file for sharing among client devices via the link Download ca.crt.
# Custom certificate
If the certificate is uploaded, this section will contain the basic certificate’s parameters. If it's not, you will find the buttons for uploading the certificate:
Use the Choose a file button to select the certificate and key files. Then click Upload.
The certificate format, key format and key correspondence to certificate are checked during download. Should just one check fail, the certificate and key files will not be not saved.
Read how to convert an existing commercial certificate to a format supported by the TrueConf Server in our knowledge base.
# Users
# User Accounts
In the User Accounts section you can add new user accounts, as well as edit and remote existing user accounts.
The maximum number of user accounts in TrueConf Server Free is 12.
Add a new user.
Search users by TrueConf ID, first name, last name, display name, or email.
View user groups available on your TrueConf Server instance.
Export the list of users to a CSV file for later import to the address book of TrueConf Group (can be done in the Maintenance section of the endpoint control panel ). This button is available only in the Registry mode. The CSV file will saved in the UTF-8 encoding and ";" will be used as a separator which means that the preference settings will be ignored.
The list of the users registered on your TrueConf Server instance. At the bottom of each user's avatar, user status is displayed:
— the user is online
— the user is offline
— the user is in a conference or in a call
— the user is the owner in the conference.
Read how to connect users from outside your network to your TrueConf Server instance in our knowledge base.
In order to change user information, click on the username. To remove a user, click on the 
button.
You cannot edit user details in LDAP mode. User data entry form is available only in Registry mode.
# User profile
Click on any user account in any control panel section to proceed to edit mode:
Switch user to active or inactive status. If the status is inactive, the user account still exists, but this user cannot log in to the TrueConf client application.
Forcefully disconnect all user’s client applications from your TrueConf Server instance. You may use this option to allow another user to connect to your server when the maximum number of connections in your license has been reached.
- TrueConf ID is a unique user identifier. It can be used for authorizing in client applications and making calls and conferences. Username is a part of your TrueConf ID displayed before the “@” symbol. It may consist of Latin characters, numbers, underscores, hyphens and dots. The server name displayed after the username (`@server` next to the input field) is required for calling a user of another TrueConf Server instance. The username is set when creating a user account and cannot be changed afterwards.
Enter the user's password. After creating or editing an account, you cannot see the password you’ve set. However, you can always change the password. To check password requirements, click on the
button which is next to the password confirmation field.User’s email address. You can set automatic email notifications to this address via SMTP server connected to your TrueConf Server instance.
The name you have entered will be displayed in the address book of other users. This field, as well as the username indicated at step 3, is prefilled. However, the field value can be changed.
User’s personal details. These fields are not required.
User groups. Click the arrow icon to view existing groups on your TrueConf Server instance. To add a user to one or more groups, check the box on the left of each group name.
If necessary, you can enter the user’s phone numbers. One can call any of these numbers by clicking on it in the user profile section of TrueConf client application.
If SIP telephony is used, you can enter a number for making SIP calls in this field. Then, the corresponding field will be displayed in the user profile in TrueConf client application. When a user clicks on this number, the call will be started in the format
#sip:<number>and the number can specified as<number>,sip:<number>, or#sip:<number>.Save changes, delete account, or return to the list of users.
If a user has entered an incorrect password multiple times in a row (the exact number will be specified in the Users → Settings section), the authorizatin via the web application will be locked for 24 hours. You can enable the access to the application manually by clicking the Unlock button on the user profile page:
At the bottom of the page you can select additional settings that will be activated in client application when the user signs in. These settings define input and output bitrate limits.
If such settings have not been configured, group settings (if any) are applied to the user (the member of the group). User group settings are displayed next to the user settings field. They are displayed for preview only and cannot be changed. If a user is a member of multiple groups, the scope of the user rights will be defined by the group with fewer rights.
User application settings have higher priority than group settings: if you put user restrictions lower than group restrictions, user restrictions will be applied.
Users can independently change bitrate settings in their client applications. But the server settings will have the highest priority.
At the bottom of the page you can find the address book and edit buttons. The address book contains all the users who are located in the address books of the user groups where the user belongs.
You can add individual entries to the list, which will be displayed only to the user being edited. Please note that you can add not only TrueConf Server users, but any call string, such as conference ID, SIP/H.323 or RTSP in the address book. Subsequently, you can delete them using the button. The user can delete them in the address book of the client application or in the personal area.
Add a user to the address book. To add a user, start typing the username or display name. From the drop-down list, select the user that matches your search (if the user is registered on your TrueConf Server instance).
The list of groups that the user belongs to, as well as the address books which are included in the user’s contact list and cannot be removed.
Search for users.
The list of users displayed in the address book. Click on the user registered on your TrueConf Server instance to edit their profile.
# Groups
In Groups tab you can create, rename, edit and delete groups. You can also add or remove users from the group, set up their address book and configure individual settings for the users of any group.
To add a new group, enter its name and press Create.
At the group level you can allow or forbid the following features:
Editing address book. By checking this field, administrator allows users to change users display names of the users, delete/add users and perform any other changes in the group’s address book. If the box is not checked, group users will not be able to perform the actions mentioned above. In this case, all changes are performed by administrator in TrueConf Server control panel and extend to all address books of the users from this group.
Making point-to-point video calls. However, users can still receive incoming calls.
Creating group conferences.
Sharing the screen and application windows
Ability to permit the remote control of one’s desktop
Slideshows
Sending files
Conference recording in the client application. This feature does not affect the ability to activate video recording when creating a conference in the application scheduler or personal area.
Operator rights. Operator right enables a group participant to become a moderator and have access to the real-time meeting management tool of any conference he or she joins.
These settings allow you to distinguish between different server users.
3. Edit the name of the group and its members.
4. Set up address book for group members.
5. Adjust bandwidth settings for group members.
6. To delete one or more groups, check corresponding boxes and click Delete selected. Accounts of the group members will not be deleted from your TrueConf Server instance.
When configuring settings for a user group, please note that guests who join your public conferences belong to the Users without group group. Any restrictions you set for this user group will apply to its users. For example, if you disable the 
box, guests will not be able to share content or application windows even if they are connected from TrueConf client applications.
You can find the examples of user group settings in the article in our knowledge base:
how to create a group in the Registry mode and add it in LDAP mode
how to configure the group address book and add SIP/H.323/RTSP endpoints and conferences to the address book.
# Editing group's name and its members
Click on the group name from the list to access the User Accounts page. Here you can rename the group and edit the list of members using the corresponding buttons:
Click the Add a user button to complete the list. Select the users you want to add to the chosen group in the window. After that they will be marked with a checkmark. After all users have been selected, click Save:
Click Rename to change the group name. Enter the new name and press Save (or press Cancel if you want to close the window without changing the settings):
# Setting up address book for users of the group
In the Address Book column of each group, click Customize. Click on it to edit the address book of this group. Group members can also add new contacts to the address book if they have a corresponding right (to enable it, please check Address Book Editing box).
You can add all users belonging to another group at once to the group’s address book (i. e. to the address book of each of its members). To that end, use Define, which users will be shown in the address book of the users in the group. Please note that automatic addition of users to the address book and manual addition are applied independently of each other.
You can also manually add users of different types (this process is similar to adding users to the address book in the user's profile). However, group members cannot delete users themselves, because these contacts are added to the entire group and not to their personal address book.
Group members can search for other TrueConf Server users and add them to their list of contacts on their own (if you have enabled address book editing).
# Setting application settings for group users
Click Customize in Application column to set bandwidth limits for the group users.
# Aliases
# Description
Thanks to aliases, you can call TrueConf Server user or any other user who can be called via the server (e.g. SIP, H.323, RTSP or other server users) using a short alias without entering full call string. By adding an alias, you create an extra name for existing user. When calling an alias, your call is redirected to the existing user corresponding to this alias.
This option is very useful for those users who are making calls to TrueConf Server users from mobile devices using a dialer. You can create digital aliases for server users so that they can be called from mobile devices.
An alias may contain numbers and letters. The maximum number of characters is 32. You can update aliases only after restart you have restarted the server.
Call string (including username of the server user). The calls to the alias will be forwarded to this user.
Press the button to add a new alias to the list.
To delete one or more aliases, mark them and click Delete selected.
After adding or removing aliases, please restart your server to update the list of aliases.
# Use for federation
In federation mode aliases can be used to make calls just like TrueConf ID. An alias will be resolved on the server which is specified after @ in the full alias@server alias , e.g., 122@video.server.name.
We will now discuss two examples of using aliases on federated TrueConf Server instances, one.name and two.name.
Case 1
Each of TrueConf Server instances has its own aliases. We have created an alias 111 for the user userA from the one.name server.
To make a call to userA from the two.name server, the following string should be entered in the address line:
111@server where server is the DNS name or IP address of the one.name server.
Case 2
Create an alias 111 on the two.name server for the user userA from the one.name server. It will correspond to the following call format:
userA@server where server is the DNS name or IP address of the one.name server.
In this case the users from the two.name server will be able to call users from the one.name server without its IP or DNS name. They will just have to enter aliases in the address line of their client application. For example, they can use 111 which we have discussed before.
The second option is more transparent for users, but in this case, it will be more difficult to configure a convenient system of aliases.
# LDAP / Active Directory
Syncing server with LDAP is unavailable in TrueConf Server Free version.
Switching between user data storage modes. TrueConf Server supports two types of data storage: Registry and LDAP. You can switch to any type by pressing Switch button:
# Registry mode
Registry mode is used by default. In this mode, the server contains information about the users on the local server. You can add or remove users via control panel. If the server has been switched from Registry to LDAP data storage mode, existing user records will not be used anymore.
When switching to LDAP data storage mode, user records stored on the local computer will not be removed, so switching to another data storage mode will not damage saved information.
# LDAP mode
In this mode the server operates information about the users from removed or local LDAP directory. In LDAP mode you cannot edit user list and user group settings via control panel. By default, configuration settings for LDAP match Microsoft Active Directory. User information is edited using Active Directory management tools.
In LDAP mode, user rights correspond to the Active Directory group where users belong. To activate this mode, check LDAP → Enable and press LDAP settings button at the bottom. LDAP settings window will open:
Server type.
Connection to the LDAP in the safe mode. Only in this case safe transmission of the user information through the network is ensured.
LDAP server settings configuration (automatic and manual).
In the automatic mode the LDAP server can be chosen among the servers by default of the DNS domain, specified in this field. Default servers are being chosen according to the relevant DNS-notes of SRV type. For Active Directory DNS domain name AD can be indicated here.
LDAP server address and port.
Base Distinguished Name is a directory object designed for searching users, e.g.
ou=People,dc=example,dc=com.- TrueConf Server authorization modes on the LDAP server.
Authorization parameters on the LDAP server.
After choosing this option the users can automatically get authorized in the system by using the current Windows user account. The option is available only for the systems working on the basis of Microsoft Active Directory. For NTLM authentication work it’s necessary that the server on which TrueConf Server software is installed is located in the same AD domain with the users.
For Active Directory in this field it’s possible to indicate LDAP group of users, who can get authorized on the TrueConf Server, e.g.
cn=TC_Users,ou=People,dc=example,dc=com. To choose an LDAP group using the Browse button you need to fill in the spaces for connection to the LDAP server (Server Settings and Authentication), including Base DN field.Additional LDAP parameters. Allow to adjust the parameters to other types of LDAP servers.
When changing from LDAP mode to Registry mode it is possible to import user data. To do this, choose the Registry mode in the User storage tab, tick on Import User Information and click on Switch.
User passwords are not imported. After being imported the user accounts are inactive (see User accounts section).
In LDAP mode, only the digest password will be available for editing in the user profile. This digest password must be specified when registering an SIP/H.323 endpoint on TrueConf Server. The same password should be specified in the authorization settings for the endpoint:
Directory of groups and users registered on TrueConf Server. This tab allows to create and manage the user’s groups. User Accounts tabs allows creating groups and managing rights. In the Registry mode a user can belong to one (or more) created groups. This parameter can be edited in the edit user information window. In the LDAP mode this window allows you to define rights for several LDAP groups. User attribute can be defined in the LDAP folder.
To import user groups from LDAP, open Users → Groups. Click the Change button and select corresponding groups in the drop-down list. Read more in our article on how to set up user groups.
On the server the Users without group is created by default.
If you have several TrueConf Server instances connected to a common LDAP directory, users can log in to the personal area from a guest page of any of the connected servers. In addition, users can participate in private meetings hosted on a different TrueConf Server instance connected to a common LDAP directory using an auto-generated login.
# Password and account lockout settings
# Password requirements
When using the Registry mode, you can specify the minimum password length (from 2 to 64 characters) and specify other requirements (upper and lowercase characters, digits, special characters) for a TrueConf Server user. These parameters will be checked when adding a new user account or changing the password. These requirements will also be applied when a user will be editing the password in the personal area.
If the password does not meet the requirements, an error message will be displayed. Click on the button (which is next to the input field) to view the password requirements:
# Automatic lockout
In this section, you can enable the account lockout policy for those cases when a user enters an incorrect password during authorization.
Here, you can specify:
account lockout period (a user can be manually unlocked at any time in his/her profile)
maximum number of failed login attempts
time interval between unsuccessful login attempts (if the interval is larger than the specified value, the counter for unsuccessful login attempts will be reset to zero).
Let us consider the following example. Here, we will use these settings:
Account lockout duration = 6:00 (6 hours);
Maximum number of failed login attempts = 5;
Reset account lockout counter after = 00:10 (10 minutes).
Then, if a user makes 5 unsuccessful authorization attempts with the login (TrueConf ID) existing on the server and the time difference between these attempts will be less than or equal to 10 minutes, the account will be locked for 6 hours.
# Group conferences
This section enables server administrators to schedule conferences, invite participants, and set other parameters.
Such conferences can be launched automatically (at a specified time or according to a schedule) or manually by server administrators.
In TrueConf Server Free, the maximum number of ongoing group conferences is 1. The number of simultaneous video calls is unlimited.
# PDF file import settings
With TrueConf Server (both free and paid license), users can enjoy a number of collaboration tools: share screen or separate application windows, show slides, control desktops remotely, etc. However, you need to set up additional third-party software to display slides created from PDF files in TrueConf for Windows client applications.
The open-source Ghostscript library is used to create a slideshow from a PDF file in TrueConf for Windows. When a user imports a PDF file for the first time, this library will be automatically downloaded from your TrueConf Server instance and installed on the user's PC. However, you need to manually pre-configure the library on the server side because it is not incorporated into TrueConf software.
TrueConf client applications for Linux and macOS use system libraries for working with PDF files. The import of these files will be available when connecting to TrueConf Server for Linux and TrueConf Server for Windows. Please contact our technical support if you have any problems or additional questions about this feature.
# TrueConf Server for Windows
Please contact TrueConf technical support to request the archive with compiled Ghostscript libraries. The archive will include four files: gsdll86.lib, gsdll64.lib, gsdll86.dll, gsdll64.dll.
Create a
third_party_extensionsdirectory in the TrueConf Server working folder (C:\TrueConf\by default).Unpack the archive from step 1.
Open the registry (for example, by running the regedit command from your console).
Go to the registry branch
HKEY_LOCAL_MACHINE\SOFTWARE\TrueConf\Server\AppProperties
and create a string parameter pdflibrary_url with the value https://[server_address]/third-party-extensions/gsdll.dll, where [server_address] is the FQDN (domain name) or IP address of your TrueConf Server instance. This address will be used for connecting to the server from client applications.
6. Open the file [installation_path]\httpconf\opt\redirects.conf, where [installation_path] is the server installation path and add the following text starting from a new line (all other line should be commented out):
RewriteEngine On
Include opt/work_dir.conf
<IfDefine work_dir>
RewriteCond %{REQUEST_URI} ^\/third-party-extensions\/gsdll.dll$
RewriteCond %{QUERY_STRING} ^(.+&)?(arch=x(64|86))(.+)?
RewriteRule ^(.*)$ "${work_dir}/third_party_extensions/gsdll%3.dll" [L,QSA]
</IfDefine>
<IfDefine work_dir>
AliasMatch ^/third-party-extensions/(.+).(.+) "${work_dir}/third_party_extensions/$1.$2"
</IfDefine>
7. Restart TrueConf Server and TrueConf Web Manager services from your Task Manager. TrueConf Web Manager service will not be affected if you restart TrueConf Server from the control panel.
# TrueConf Server for Linux
The commands listed below need to be executed with superuser privileges or using sudo (e.g., sudo command). Please note that sudo may be unavailable by default in your operating system. You can check its availability using the sudo -V command.
Please contact TrueConf technical support to request the archive with compiled Ghostscript libraries. The archive will include four files: gsdll86.lib, gsdll64.lib, gsdll86.dll, gsdll64.dll.
Create the redirect configuration file, e.g., with nano editor in the terminal:
nano /opt/trueconf/server/etc/webmanager/opt/redirects.conf
3. Write the following lines to the configuration file and save it:
RewriteEngine On
Include /opt/trueconf/server/etc/webmanager/opt/work_dir.conf
<IfDefine work_dir>
RewriteCond %{REQUEST_URI} ^\/third-party-extensions\/gsdll.dll$
RewriteCond %{QUERY_STRING} ^(.+&)?(arch=x(64|86))(.+)?
RewriteRule ^(.*)$ "${work_dir}/third_party_extensions/gsdll%3.dll" [L,QSA]
</IfDefine>
<IfDefine work_dir>
AliasMatch ^/third-party-extensions/(.+)\.(.+) "${work_dir}/third_party_extensions/$1.$2"
</IfDefine>
4. Add a parameter with a link for loading the necessary libraries in the application by running this command:
/opt/trueconf/server/bin/vcs/tc_regkey set "AppProperties" "pdflibrary_url" str "https://[server_address]/third-party-extensions/gsdll.dll"
where [server_address] is the FQDN (domain name) or IP address of TrueConf Server that will be used for connecting to the server from client applications.
5. Create a directory for libraries:
mkdir /opt/trueconf/server/var/lib/third_party_extensions
6. Unpack all files from the archive (received at Step 1) to the third_party_extensions directory.
7. Restart the web server services and the main TrueConf Server service:
systemctl restart trueconf-web
systemctl restart trueconf
# Conference list
This list includes the following events:
events created by administrator in this section of the TrueConf Server control panel
events added by users in the application or personal area
active conferences created ad hoc in the client applications (they will disappear from the list when they end).
Here you can do the following actions:
Filter the list by the conference name or ID.

Enable the use of PIN to join the conference. PIN boosts your meeting security and protects your conference from third-party access (even if a third party has a conference join URL in case you organize a webinar). PIN will be generated automatically upon checking the box. However, you can always change the PIN in the field below.
PIN-protected meetings can be joined only from TrueConf client applications and browsers (via WebRTC).
To join a PIN-protected conference from an SIP/H.323 endpoint, it is necessary to add PIN, separated by a comma after the conference ID in the call string:
00<conf_id>,pin@<trueconf_server>:<port>
3. Manually set your PIN or refresh it using the

6. Press to activate video conference recording (see Recordings section).
7. Press to setup streaming.
8. Select the streaming preset (see Streaming).
9. Turn on UDP Multicast mode. With UDP Multicast you can use network resources more efficiently because conference participant streams are directed bypassing the server. In this mode video and audio streams are transferred inside UDP Multicast domain. These domains can be used in the local network or VPN. Please check your license to see if this mode is available for you.
If UDP Multicast mode is enabled while you are trying to connect to the conference using third-party protocols (WebRTC, RTSP, SIP, H.323, etc), video conference recording and streaming will be unavailable.
Enabling this function is recommended only for those users who have hands-on experience in the sphere of network administration. Please note that it is your responsibility to check if this technology is available in your network.

11. Enable email invitations for conference participants. This option is available only for scheduled conferences providing the SMTP server integration is set up.
When editing a previously created conference, this option is disabled regardless of the conference settings configured earlier. This is specifically designed to prevent the invitations from being mistakenly resent when editing an event. If you need to reactivate conference invitations (e.g., when adding participants), please manually activate the Send email invitations to conference participants checkbox.
12. Specify the conference location. The location will be displayed in the Information tab on the conference page and in the list of conferences).
13. Adding guide text to the scheduled event (e.g. presentation description or event program). This text will be displayed on the conference page.
Restrictions for webinars
If you check the Public conference (webinar) box when creating the conference, this tab will also contain permission settings for guest users:
Permission settings for guest users
This parameter is used to restrict the number of guests in the selected webinar (by default they can join the event up until the moment when the licence limit for guest connections is reached). This may be helpful when multiple webinars are held at the same time and it is necessary to distribute guest connections between them or if the rules of your event impose restrictions on the number of attendees (e.g., if it is a lecture):
Users of Mozilla Firefox, Safari, Google Chrome and other Chromium-based desktop and mobile browsers can participate in conferences via WebRTC. The number of guest connections is limited by your license.
# "Registration" tab
The Registration tab will be displayed if a public conference (webinar) is created. Here, you can configure registration settings for conference participants who want to sign up for your online event (this option will be available only for a scheduled conference):
Enable registration (disabled by default)
Specify the time when the registration will be closed:
Without limitation — available only for a recurring conference (registration for such an event will be constantly open)
At conference start — the registration will be closed right after the webinar start
At conference end — the registration will be available up until the conference end
Custom date and time — set a custom period during which the registration will be open.
3. Automatically close the webinar registration when the maximum number of participants (depends on the conference mode) is reached.
4. Allow any authorized user to join the conference after its start. In this case, any user registered on your server can sign in on the conference page and add oneself to the list of invited participants by clicking on the Attend button.
5. Settings for the input fields in the registration form. You can drag and drop input fields to create a custom registration form. Besides, you can mark the corresponding checkboxes to make sure that certain fields must be filled by participants. The customization of registration form is available only when a conference is created. This feature is not available when the conference is edited.
6. You can select the input fields that should be displayed during registration only when creating a conference. Сlick on the Add field button to specify both standard and custom fields (up to 10 ):
When the changes are saved, users will be able to sign up for a public conference on its web page. To learn more about this feature, check out the TrueConf Server user guide:

# API
# OAuth2
This section is used to manage applications or services which utilize TrueConf Server API. Permissions are controlled based on OAuth 2.0. protocol. You can learn more information about OAuth 2.0. protocol in RFC 6749 official documentation (opens new window) or in the note below.
Oauth 2.0 is used to authorize certain applications (clients) to access protected resources with limited scopes and rights. With this approach, you can block a particular application or a user from the server resources at any given period of time. The protocol also allows you to authorize third-party applications and do actions on the server on behalf of the user via API. In this case, the user does not need to give their username or password to any third-party application (Authorization Code method).
After authorization on TrueConf Server using OAuth 2.0 protocol, every third-party application obtains an access token. Those applications with a valid access token can access TrueConf Server API. The list of API commands can be found in [TrueConf Server API documentation]. TrueConf Server administrator can manage third-party application permissions and access tokens obtained via this section.
Learn more about TrueConf API use cases in our blog.
After successful authorization, the application receives access token with a limited lifespan and scope (server wide or limited to a specific user). For example, server wide scope gives information about any conference on the server, while user’s scope provides the information only about those conferences where the user is the conference owner or a listed participant. The scope is defined by the authorization type selected by a third-party application developer, while permissions set (rights) are determined by TrueConf Server administrator for every application.
| OAuth 2.0 authorization method | Access token scope | Authorization result |
|---|---|---|
| Client Credentials The client gets access token, the scope of which is server wide. User authorization is not performed. This method is recommended for trusted applications only. | Server wide | Access token valid for 24 hours is issued. |
| User Credentials (a.k.a. Resource Owner Password Credentials Grant)
To obtain access token, it is required to provide username and password received on the application side. | User’s scope | Access token valid for 24 hours and (refresh token) valid for 14 days are issued. |
| Authorization Code Access token is issued after user has successfully authorized on TrueConf Server special web page. The application cannot access username and password of the user. | User’s scope | Access token valid for 24 hours and refresh token valid for 14 days are issued. |
| Refresh Token This method is used to obtain a new access token based on your existing refresh token. | Equal to scope of the user who has received refresh token initially | Access token valid for 24 hours is issued. This method cannot be used to obtain new refresh token. |
When requesting an access token, it is required to indicate Application ID and Secret. These parameters can be obtained and updated by creating or editing the application in this section. Application ID is created automatically and cannot be changed later. By contrast, application secret can be further regenerated.
# Permissions
API capabilities of a third-party application depend on the permissions it obtained.

Each method is assigned with a set of permissions required for successful method call. All sets of permissions are specified in TrueConf Server API documentation.
If an OAuth application requires both read and write access to a certain parameter, then you can specify a general permission <permission> instead of specifying <permission>:read and <permission>:write permissions, if it is available. For example, you don't need to click both users:read and users:write checkboxes to allow an application to read and edit TrueConf Server user accounts. Instead, you can select only the users checkbox.

In this field, you can also specify network path if TrueConf Server service has the rights to place recordings in this directory.
You cannot change the path to the conference recordings directory in the TrueConf Server for Linux control panel. If you need to store recordings in another directory, we recommend using symbolic links (symlinks).
2. Enable/disable point-to-point video call recording. This option is similar for all calls: either all are recorded, or none are recorded. Please note that if you enable this option, you will not able to use direct connection between users (to be recorded, all information between subscribers is transferred through the server).
3. There are three options to set up group conference recordings: either all are recorded, or none are recorded, or recording is set separately for each conference ("on demand" mode).
4. The video format in which the recording files will be saved. To preview the conference recording, select the MP4 format in the control panel.
5. Time (in days) after which conference recordings should be deleted automatically. Click the checkbox next to the field to activate the text field. If you don’t check this box, recordings will be stored indefinitely (recordings are not deleted automatically).
Can the video recorded with TrueConf Server be played using third-party programs?
Yes, it can. In order to do it you will need to download and install a media player with VP8 video codec support, e.g. VLC (opens new window).
You can also upload any of your recordings to YouTube to share with your colleagues.
