I'm testing Linphone against reConServer[1] in Conference mode
When the first user joins, reConServer puts them on hold When the second user joins, reConServer tells the first user to resume reConServer sends a re-INVITE to Linphone with a correct SDP offer for IP4: INVITE sip:[email protected]:5061;transport=udp SIP/2.0 Via: SIP/2.0/UDP 10.1.2.4:5068;branch=z9hG4bK-524287-1---eb6a6d6512e04841;rport Max-Forwards: 70 Contact: <sip:[email protected]:5068> To: "Daniel" <sip:daniel@[2001:....]>;tag=UC35Qmlxe From: <sip:[email protected]>;tag=85e07e2d Call-ID: 47~bZJRCOW CSeq: 2 INVITE Session-Expires: 1800;refresher=uac Min-SE: 90 Accept-Language: en Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, NOTIFY, SUBSCRIBE, UPDATE, PRACK, INFO Content-Type: application/sdp Supported: replaces, timer, norefersub, answermode, tdialog User-Agent: reConServer 1.13.0~alpha1 Content-Length: 239 v=0 o=- 1618481455257285 1618481455257285 IN IP4 10.1.2.4 s=- c=IN IP4 10.1.2.4 t=0 0 m=audio 17390 RTP/AVP 0 8 97 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:97 telephone-event/8000 a=fmtp:97 0-15 a=ptime:20 a=sendrecv sigcomp id= Linphone responds to the re-INVITE with 200 OK.

Then it creates a valid SDP answer with a valid IP address. _______________________________________________ Linphone-users mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/linphone-users
