Hi, i am testing a proxy using sipp but i have problem with Via headers. 10.0.0.1 is the proxy. 10.0.0.2 is the sipp server (-sn uas) 10.0.0.3 is the sipp client (-sn uac)
I have noticed that the 2nd via added by sipp uas is threat incorrectly by the proxy but i don't know if it is my fault. Here the sip flow. > 1) The sipp uac send to the proxy the INVITE: > INVITE sip:[email protected]:5060 SIP/2.0 > Via: SIP/2.0/UDP 10.0.0.3:5060;branch=z9hG4bK > From: sipp <sip:[email protected]:5060>;tag=23603SIPpTag091 > To: sut <sip:[email protected]:5060> > Call-ID: [email protected] > CSeq: 1 INVITE > Contact: sip:[email protected]:5060 > Max-Forwards: 70 > Subject: Performance Test > Content-Type: application/sdp > Content-Length: 186 > > v=0 > o=user1 53655765 2353687637 IN IP4 10.0.0.3 > s=- > c=IN IP4 10.0.0.3 > t=0 0 > m=audio 6000 RTP/AVP 8 101 > a=rtpmap:8 PCMA/8000 > a=rtpmap:101 telephone-event/8000 > a=fmtp:101 0-11,16 > > > 2) The proxy send the INVITE to sipp uas, adding the second Via header > INVITE sip:[email protected]:5060 SIP/2.0 > Record-Route: <sip:10.0.0.1;lr=on;ftag=23603SIPpTag091;did=c04.37fe035> > Via: SIP/2.0/UDP 10.0.0.1;branch=z9hG4bK21dd.7d5758a6.0;rport > Via: SIP/2.0/UDP 10.0.0.3:5060;rport=5060;received=10.0.0.3;branch=z9hG4bK > From: sipp <sip:[email protected]:5060>;tag=23603SIPpTag091 > To: sut <sip:[email protected]:5060> > Call-ID: [email protected] > CSeq: 1 INVITE > Contact: sip:[email protected]:5060 > Max-Forwards: 69 > Subject: Performance Test > Content-Type: application/sdp > Content-Length: 187 > > v=0 > o=user1 53655765 2353687637 IN IP4 10.0.0.3 > s=- > c=IN IP4 10.0.0.1 > t=0 0 > m=audio 50110 RTP/AVP 8 101 > a=rtpmap:8 PCMA/8000 > a=rtpmap:101 telephone-event/8000 > a=fmtp:101 0-11,16 > > > 3) The sipp uas does not properly recognize (maybe) the 2nd Via and send back > this (please note the line after the first Via) > SIP/2.0 180 Ringing > Record-Route: <sip:10.0.0.1;lr=on;ftag=23603SIPpTag091;did=c04.37fe035> > Via: SIP/2.0/UDP 10.0.0.1;branch=z9hG4bK21dd.7d5758a6.0;rport, SIP/2.0/UDP > 10.0.0.3:5060;rport=5060;received=10.0.0.3;branch=z9hG4bK > From: sipp <sip:[email protected]:5060>;tag=23603SIPpTag091 > To: sut <sip:[email protected]:5060>;tag=15130SIPpTag011 > Call-ID: [email protected] > CSeq: 1 INVITE > Contact: <sip:10.0.0.2:5060;transport=UDP> > Content-Length: 0 Is it my fault ?
