Currently, Matrix VoIP calls do not work when the clients are on different networks (which they almost always are). Coturn logs a message like ERROR: A peer IP 192.168.100.91 denied in the range: 192.168.0.0-192.168.255.255. There has been a workaround in 59655fd1b0, which enables plain connections. However, (D)TLS connections are more desirable.

The testing tool mentioned in the Synapse docs shows that the plain connections work, but (D)TLS connections (turns:) do not. Also, it shows plain turn to not be working over IPv6?
