My SIP provider rewrites SDP (answer on video call without video). Original lines: m=video 0 RTP/AVP 97 96 c=IN IP4 212.53.40.76 b=TIAS:256000 Modified: m=video 23124 RTP/AVP 97 96 c=IN IP4 212.53.40.76 b=TIAS:256000 a=inactive PJSIP terminates call after receiving modified SDP. Is modified SDP conforms to SIP standard? Is this problem of SIP server or PJSIP? Thank you. -------------- next part -------------- An HTML attachment was scrubbed...
