I installed Synapse and Riot and since I had a problem for video-calls, I investigated the issue and found that it is necessary to install a Turn server to run video-calls through NATs.
Then I realized that it was installed and configured during the installation of Synapse. However the configuration does not work for me.
I have several questions:
What is the difference between “/etc/turnserver.conf” and “/etc/matrix-synapse/coturn.conf”? Which file should I take into account? This webpage indicates that I should use the first file, however in my server, the second file is already customized.
Hence this second question. In the file “/etc/matrix-synapse/coturn.conf” the domain name for the Turn server is the same as for Synapse ; is it normal?
I also found out that the port 5349 is used by the Turn server, maybe it would be convenient to add a request for opening this port during installation?
I used “turnserver -v” in order to try to detect an issue, but even during a call, nothing new appears. Is that an issue in itself? Regardless, this shows that Turn is listening on ports 3478 and 3479 which is in contradiction with coturn.conf but is agreement with turnserver.conf…
I am bit lost with this Turn server configuration. Has someone been having the same issues?
