Configuring the MMP
4.9 Configuring the TURN Server
1. If necessary, SSH into the MMP.
2. Configure the TURN server with the following command:
turn credentials <username> <password> <realm>
The following is an example where username is myusername, the password is mypassword
and it uses the realm example.com.
turn credentials myusername mypassword example.com
3. If required, set the public IP Address that the TURN Server will advertise using:
turn public-ip <ip address>
Note: If the TURN server has a public IP address rather than being NAT’ed (see the figure
below and its notes), this step is not required, go on to step 4.
The following is an example where a public IP address is set to 5.10.20.99
turn public-ip 5.10.20.99
Note: The IP address set here should not be confused with the IP addresses set in the Web
Admin Interface Configuration > General page later in this guide. The MMP commands
configure the TURN server itself, while the Configuration > General page settings allow
the Call Bridge and external clients to access the TURN server, and are explained in
section 10.
Figure 4: TURN server public IP address
Note: * Although the port range between the TURN server and the External clients is shown as
32768-65535, currently only 50000-51000 is used. The required range is likely to be larger in
future releases.
