Hi All;

 

I want to use freeswitch to set up a WebRTC POC (Audio only, udp/tls/rtp/savp).  Setup is Anonymous (192.168.199.216/chrome/sipjs:sip-0.7.0.min) ->freeswitch (192.168.199.22) ->1010 (192.168.199.216/chrome/sip-0.7.0.min),just following the information in book “FreeSWITCH 1.6 Cookbook”.

If using media bypass mode (inbound-bypass-media == true), all works fine, caller and called can hear each other.

But if disabling media bypass mode, call is rejected by FS.

 

FS log shows “[ERR] mod_sofia.c:2299 CODEC NEGOTIATION ERROR. SDP”. Attachment is detailed FS log file.

Chrome uses opus 111, FS uses opus 116.

Mod_sofia.c::sofia_receive_message() --> sofia_media.c::sofia_media_negotiate_sdp() --> sofia_core_media.c::sofia_core_media_negotiate_sdp().

 

Help is needed to troubleshoot this issue.

 

Thanks advance.

Smile.
