Calls don't work

[quarckster]

A connection seems established, but there is no audio during the call.

Sorry. This is a telegram bug. They are working on this.

@schors can you tell about it? I've never heard about this.

[schors]

No. I can't

docker ps -a
docker stop tgdante
docker cp <ContainerID>:/conf/dante.conf .

Add before socks block:

socks pass {
    from: 0.0.0.0/0
    to: 0.0.0.0/0
    # udp.portrange: 40000-45000
    command: udpassociate
    log: error connect disconnect
}

socks pass {
    from: 0.0.0.0/0
    to: 0.0.0.0/0
    command: udpreply
    log: error connect disconnect
}

Save:

docker cp dante.conf <ContainerID>:/conf/dante.conf

docker start tgdante

Add Iptables rules:
-A INPUT -p udp -m multiport --dports 40000:45000 -j ACCEPT
Save:

Complete!

@satoshinakamotoofficial's solution works for me. There also was a bug in libtgvoip that prevented TCP fallback and I've fixed that recently. The fixed library is already in the Android app, and other apps will follow soon. While sending voice over TCP isn't generally a great idea, sometimes it's better than nothing.
