Hello, I am trying to make Linphone work with a VLC server through the gateway which translates messages between SIP and RTSP. Eventually I want to listen/view video streamed by a VLC server on Linphone client. Linphone, gateway and VLC are running on the same machine. But, I am getting error regarding 'No codec intersection'. Looking at the Linphone debug log, it details error as 'error: Incompatible SDP offer received in 200Ok, need to abort the call'.
This is an initial INVITE message from Linphone: -------------------------------------------------------------------------------------------------------------- INVITE sip:[email protected]:33000 SIP/2.0 Via: SIP/2.0/UDP 192.168.111.215:5060;rport;branch=z9hG4bK247713395 From: <sip:[email protected]>;tag=1981465341 To: <sip:[email protected]:33000> Call-ID: 230194435 CSeq: 20 INVITE Contact: <sip:[email protected]> Content-Type: application/sdp Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, NOTIFY, MESSAGE, SUBSCRIBE, INFO Max-Forwards: 70 User-Agent: Linphone/3.4.3 (eXosip2/3.3.0) Subject: Phone call Content-Length: 320 v=0 o=yatin 446 446 IN IP4 192.168.111.215 s=Talk c=IN IP4 192.168.111.215 t=0 0 m=audio 7078 RTP/AVP 112 111 110 0 0 3 0 8 101 a=rtpmap:112 speex/32000 a=fmtp:112 vbr=on a=rtpmap:111 speex/16000 a=fmtp:111 vbr=on a=rtpmap:110 speex/8000 a=fmtp:110 vbr=on a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-11 -------------------------------------------------------------------------------------------------------------- This is a 200 OK response from the gateway -------------------------------------------------------------------------------------------------------------- SIP/2.0 200 OK Via: SIP/2.0/UDP 192.168.111.215:5060;rport;branch=z9hG4bK247713395 From: <sip:[email protected]>;tag=1981465341 To: <sip:[email protected]:33000>;tag=random Call-ID: 230194435 Contact: <sip:[email protected]:33000> CSeq: 20 INVITE Max-Forward: 70 Content-Type: application/sdp Content-Length: 111 v=0 o=yatin 446 446 IN IP4 192.168.111.215 s=Talk c=IN IP4 192.168.111.215 t=0 0 m=audio 50140 RTP/AVP 112 -------------------------------------------------------------------------------------------------------------- Can anybody please help me with debugging of this issue.
