[SR-Users] 488 Not Acceptable Here when remove codecs with rtcp-fb

[José Lopes]

Hello Daniel,

Thanks for your reply.

On the next link, I put the original SDP from webrtc client and the SDP
after kamailio that exposes the issue.
I am using Kamailio version 5.3.3 with sdpops and rtpengine module.
