Hi, I am using sip accounts from opensips.org for testing. using TCP as sip transport.
I find server changes the "c=" line to server's public address, and this make ice mismatch because the server public address is not in ice candidate list. Is it normal? Any suggestion. caller send: INVITE sip:aaaaaaaaa...@opensips.org;transport=tcp SIP/2.0 Via: SIP/2.0/TCP 192.168.0.2:3719 ;rport;branch=z9hG4bKPj38e9f128d29b4da08f32c904 a14a808d Max-Forwards: 70 From: sip:bbbbbbbbb...@opensips.org;tag=0f01868840054feaae85bb57fac2c895 To: sip:aaaaaaaaa...@opensips.org Contact: <sip:bbbbbbbbbbbb@192.168.0.2:5060;transport=TCP;ob>;+sip.ice Call-ID: 24a38e6ab95b43a6bad890246459c2d5 CSeq: 18457 INVITE Allow: PRACK, INVITE, ACK, BYE, CANCEL, UPDATE, SUBSCRIBE, NOTIFY, REFER, MESSAG E, OPTIONS Supported: replaces, 100rel, timer, norefersub Session-Expires: 1800 Min-SE: 90 Content-Type: application/sdp Content-Length: 1818 v=0 o=- 3538405122 3538405122 IN IP4 125.114.188.111 s=pjmedia c=IN IP4 125.114.188.111 b=AS:352 t=0 0 a=X-nat:5 m=audio 64197 RTP/AVP 0 8 96 c=IN IP4 125.114.188.111 b=TIAS:64000 a=rtcp:64567 IN IP4 125.114.188.111 a=sendrecv a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:96 telephone-event/8000 a=fmtp:96 0-15 a=ice-ufrag:575360bf a=ice-pwd:5c673cd6 a=candidate:Sc0a80002 1 UDP 1694498815 125.114.188.111 64197 typ srflx raddr 192 .168.0.2 rport 3957 a=candidate:Hc0a80002 1 UDP 2130706431 192.168.0.2 3957 typ host a=candidate:Hc0a87901 1 UDP 2130706431 192.168.121.1 3957 typ host a=candidate:Hc0a80301 1 UDP 2130706431 192.168.3.1 3957 typ host a=candidate:Sc0a80002 2 UDP 1694498814 125.114.188.111 64567 typ srflx raddr 192 .168.0.2 rport 3960 a=candidate:Hc0a80002 2 UDP 2130706430 192.168.0.2 3960 typ host a=candidate:Hc0a87901 2 UDP 2130706430 192.168.121.1 3960 typ host a=candidate:Hc0a80301 2 UDP 2130706430 192.168.3.1 3960 typ host m=video 63577 RTP/AVP 97 c=IN IP4 125.114.188.111 b=TIAS:256000 a=rtcp:60443 IN IP4 125.114.188.111 a=sendrecv a=rtpmap:97 H264/90000 a=fmtp:97 profile-level-id=42e01e;
