# Benefits of TrueConf video conferencing

TrueConf Server video conferencing system provides a number of advantages and unique technologies.

Relatively low system requirements

You do not need a powerful server to deploy TrueConf Server. Instead, you can use a PC based on a modern Intel or AMD CPU and choose between Microsoft Windows Server or Linux operating systems. You can find system requirements for common configurations in our article.

Convenient administration

TrueConf Server has a number of features that can simplify its administration:

  • TrueConf’s proprietary protocol that works with TrueConf client applications using a single TCP port.
  • Operation in LAN/VPN of any configurations, including satellite communication channels.

  • Synchronization with user and group directories via LDAP protocol.

  • Endpoints (PC, browsers and mobile devices) do not need to have a direct IP address for communication.

  • Works through NAT, Firewall and Proxy.

Advanced data transmission technologies

TrueConf Server uses the following technologies to improve the quality and reliability of video communication:

  • dynamic adjustment of data transmission rate

  • scalable video coding (SVC)

  • direct connection priority using Hole punching technology

  • automatic connection restoring if the connection fails

  • adaptive buffer for incoming audio and video data streams.

4K video conferencing

You can also manually set up conference streaming to other third-party services, for example, Facebook.

Managing video layouts and participants’ devices

TrueConf Server users can configure video layouts, manage devices of conference participants, and use other options for streamlining meetings:

# Video calls and group video conferences

Depending on your business tasks, you can choose from a number of conferencing modes available with TrueConf Server.

# What is a video call?

A video call is a video communication session between two users who can see and hear each other.


TrueConf provides a number of additional options during video calls: chat, file sharing, content sharing (e.g. sharing screen or separate application windows) and other collaboration tools.

You can learn more about video calls on our website, check out our system requirements and read how to make video calls in client applications for various operating systems: Windows, Android, Android TV, iOS.

# What is a video conference? Types of video conferences

Video conference is a video conferencing session between more than two users.


With TrueConf Server you can organize video conferences of the following types:

  • Private. Secure conference available to users authorized on your TrueConf Server instance or on a federated TrueConf Server instance. Private conferences can also be accessed by third-party SIP/H.323 and RTSP devices if they have received a conference ID (e.g., in an email invitation).

  • Public (webinar). Public conferences are organized for guests (users that do not have an account on your TrueConf Server instance) and can be easily accessed by anyone with a link or by following an email invitation. If you do not have Public Web Conferences extension enabled on your server, this conference type will be unavailable.

TrueConf group conferences may also have different launch types:

  • Scheduled. Video conference with a specific start date and time and duration of the event. It is possible to schedule a conference to be launched weekly on certain days (e.g., on Tuesdays and Fridays).

  • Virtual room. Permanently available video conference that doesn’t have a specified start or end time. You can learn more about virtual rooms in our article.

Read our step-by-step guide to learn how to join a meeting.

TrueConf Server administrator can create any group video conference and view information about ongoing or scheduled conferences in the control panel. TrueConf Server users can perform similar actions in their personal area or in the scheduler available from their client applications.

You can check system requirements for different video conferencing modes here.

# Video conferencing modes

# Extensions

TrueConf Server basic features can be extended with a number of available extensions and add-ons. Contact us to request a free trial of any extension or purchase it, our managers will be happy to help you.

# SIP / H.323 / RTSP gateway

You can use this extension to connect third-party devices to your TrueConf meetings, for example:

With TrueConf Server Free, you can have one SIP/H.323/RTSP connection for free.

The gateway acts as a gatekeeper or SIP registrar for third-party devices that will be displayed as regular TrueConf users in the address book.

# Integration with LDAP and Active Directory

With this extension, you can synchronize user information between the TrueConf Server address book and your company's LDAP directory service (e.g., Active Directory). Administrators can centralize and automate user account management operations, such as adding new users or removing ex-employees, resetting passwords, or keeping user data up to date.

# Public Web Conferences

With this extension you can organize public web conferences available to users that do not have an account on your TrueConf Server instance. This feature is typically used for conducting webinars.

Each public web conference has an external web page that contains a conference description and provides information on how to connect to it. You can also embed a public web conference to your website with a widget.

With TrueConf Server Free, you can organize public web conferences with 1 guest connection. If you would like to add more guest connections to your license, please contact us to request a free trial or purchase the extension.

# UDP Multicast

With UDP Multicast, the media data goes directly from user to user, bypassing the server. This significantly reduces the load on the network and your video conferencing server and allows you to use video communication in networks where TCP traffic is prohibited.

Please note that conference recording, WebRTC conferences and RTSP streaming are not supported in the UDP Multicast mode.

# Streaming

With this extension you can stream video conferences to third-party platforms or content delivery services such as CDNvideo, YouTube, Facebook or Wowza. If you stream your conference, you can reach millions of viewers, as their number can only be limited by the capabilities of your preferred streaming platform.

# Federation

You can use the Federation extension to make calls between users of multiple TrueConf Server instances deployed in different branches within your network. Thanks to this feature, you can also contact other companies that use TrueConf solutions (both on-premises or cloud-based).

In the federation mode, users of your TrueConf Server instance can call and invite other TrueConf users to conferences and vice versa.

Federation is a basic feature included in every TrueConf Server standard license. To enable federation, you need to purchase any TrueConf Server paid license.

# TrueConf Directory

This extension allows users of your TrueConf Server instance to search for users/groups on all TrueConf servers synchronized with it and add them to the address book. TrueConf Directory offers a global address space available in all client applications.

# TrueConf SDK for developers

With TrueConf SDK you can develop your own video conferencing applications based on TrueConf technologies or integrate video conferencing to an existing application or website.

TrueConf provides libraries for all popular desktop (Windows, Linux, macOS) and mobile (iOS, Android) platforms.

An example of an application created using TrueConf SDK is TrueConf Kiosk, a video-enabled customer care solution.

# Choose your license

You can choose one of the available licensing options: TrueConf Server Free, TrueConf Server, and a free 3-week trial version. You can find a detailed license comparison here or calculate your license price on our website.

If you would like to request a 3-week trial version of TrueConf Server, please contact us, we will be happy to help.

TrueConf Server Free provides basic features for video conferencing; however, it also has certain limitations. TrueConf Server Free is a great solution for small and medium-sized businesses to get acquainted with TrueConf benefits and deploy a self-hosted video conferencing system.
