Configuring Protocols

SIP Settings

To enable your terminal to use the SIP protocol, configure it in the Settings → Protocols → SIP section.

1. Enable SIP support.

2. Select the protocol for streaming the presented content in the BFCP transport menu: UDP or TCP.

3. If necessary, enable SRTP encryption.

4. On the SIP Server Registration tab, activate the Use SIP Server option. Additionally, you can select the SIP Transport to be used.

5. To save the settings, click Apply.

Additionally, you can configure the outgoing SIP call server:

1. Activate Use server for outgoing calls.

2. Enter the address.

3. Enter the username (TrueConf ID) and password.

4. To save the settings, click Apply.

If the entered data is correct, the text in the section will change to Registered.

H.323 Settings

To configure the H.323 protocol through the terminal's main menu, use the remote control to navigate to Settings → Protocols → H.323.

1. Enable H.323 support.

2. 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.

• On the tab, specify the H.323 Alias and H.323 extension (E.164) for calls to TrueConf Group without needing to enter the terminal's IP address (otherwise, the system name will be used as the default value).

Additionally, you can configure the gatekeeper for outgoing H.323 calls:

1. Activate Use server for outgoing calls.

2. Specify the Gatekeeper address (if choosing manual entry).

3. Enter the Gatekeeper login and Password for authorization (if required).

4. To save the settings, click Apply.

If the entered data is correct, the text in the section will change to Registered.

1. Public IPv4 address (WAN). Specify the public (external) IP address of your TrueConf Group, such as the WAN IP of the router it is connected to.

2. Ports with a range for protocols:

• RTP

• H.245 (TCP)

• BFCP (UTD, TCP).

3. H.323 Settings:

• H.460.18 Signaling Traversal;

• Media traversal (H.460.19).

4. :

• Use ICE;

• Use TURN.

5. TURN Settings. Specify the TURN server, username, and password.

When factory settings of TrueConf Group are restored, the port ranges will take the values set for TrueConf Server by default.

RTP QoS

In the section, you can set:

• MTU limit for the size of data transmitted over the network (RTP packet size excluding UDP and IP). headers);

• QoS method of traffic prioritization (QoS) – DSCP or IP Precedence. QoS label settings are available for the chosen method.
