# Configuring Protocols
# H.323 Settings
To configure the H.323 protocol through the terminal's main menu, use the remote control to navigate to the Configuration → Network → H.323 section.
Enable H.323 support.
H.323 extension (E.164) and H.323 Alias in case of calls from devices within the gatekeeper without the need to indicate the TrueConf Group IP address (otherwise the system name will be used as a default value)
In the H.235 encryption menu, select if it is necessary to use H.235 encryption:
Off – is not used
Optional – encryption is preferred, but not required which means that the connection will be established if the encryption is not configured on the far-end side
Mandatory – TrueConf Group will not connect to the endpoints if they do not support H.235 encryption.
4. If necessary, configure NAT traversal via H.460.18 and H.460.19 in the NAT traversal menu.
5. To register the endpoint on an external H.323 gatekeeper, go to the Registration section:
Choose Discover in Gatekeeper use: to find its address in the network or Manual to enter the address manually
Specify if it is necessary to use the gatekeeper for outgoing H.323 calls
Address (in case of manual input)
User name and Password for authorization (if necessary)
# SIP Settings
To enable your endpoint to use the SIP protocol, configure it in the Configuration → Network → SIP section.
Enable SIP support.
If necessary, enable Spam protection. This feature is useful when the endpoint becomes available via SIP from outside the local network. In this case, it can be attacked by different types of malware that looks for poorly protected corporate IP PBX systems to forward traffic. These attacks are spam calls to the endpoint. When antispam protection is enabled, TrueConf Group software identifies such calls by their characteristic features and ignores them.
Choose the protocol to stream content to be shared in the BFCP transport menu: UDP or TCP.
If necessary, enable SRTP encryption.
In the NAT traversal menu, you can set how to use ICE and TURN protocols and indicate the NAT server address and its authorization data.
You can register TrueConf Group with the external SIP server in the Registration menu where you can indicate the registration data and transport protocol to be used.
# NAT Settings
To configure NAT traversal, go to the Configuration → Network → NAT section:
Specify the public (external) address of your TrueConf Group, for example, WAN IP of the router to which the endpoint is connected.
Set the ranges for RTP, H.245, and BFCP ports.
When factory settings of TrueConf Group are restored, the port ranges will take the values set for TrueConf Server by default.
# RTP Settings
In Configuration → Network → RTP section, you can set:
Limited size of MTU data to be transmitted (RTP packet size excluding UDP and IP headers)
Method of network traffic prioritizing (QoS) and QoS marks settings for audio and video
