Open admin-toneca opened this issue 1 year ago • 0 comments

Describe the bug Freeswitch ignore param mono in opus.conf.xml for mono call and send stereo=1 in SDP to B-leg.

To Reproduce Steps to reproduce the behavior:

  1. Set mono in opus.conf.xml <param name="mono" value="1"/>
  2. Set inbound-late-negotiation=true and inbound-codec-negotiation=generous
  3. Send SDP in INVITE to A-leg: a=rtpmap:96 opus/48000/2 a=fmtp:96 useinbandfec=1;maxaveragebitrate=64000; stereo=0; sprop-stereo=0
  4. FreeSWITCH send to B-leg: a=rtpmap:102 opus/48000/2 a=fmtp:102 useinbandfec=1; maxaveragebitrate=30000; maxplaybackrate=48000; ptime=20; minptime=10; maxptime=40; stereo=1

Expected behavior FreeSWITCH should send INVITE to B-leg without stereo=1
