[Freeswitch-users] One way audio case between FS and Chrome on WebRTC.

[Vallimamod Abdullah]

Hi,

Have you tried disabling STUN?
Does it work in the same LAN?

There are many "Sending RTCP NACK" lines in your logs, meaning that fsw is not receiving all the RTP from your endpoint. It may be related to the stun or you may need to check your network.

Hope this helps.


Best Regards,
