According to the rule in RFC 3261, target URI is taken from the Contact header of target request/response, so I don't think it's wise to change this behavior. So it looks like the only solution is to fix the other UA to send proper address in its Contact header. -benny > > Here is my example flow: > > > > First Request > > > > Request-Line: SUBSCRIBE sip:alice at something.net SIP/2.0 > > Message Header > > Via: SIP/2.0/UDP > 178.3.3.34:5070;rport;branch=z9hG4bKPj0dd2f0bdaa84483dae84722717995f44 > > Max-Forwards: 70 > > From: sip:bob at something.net;tag=b92c03ec9bfc4a5a882d99bdb71b7a3f > > To: sip:alice at something.net > > Contact: <sip:bob at 178.3.3.34:5070;transport=UDP> > > Call-ID: c1103045184c4e088b6f9c96ceefff24 > > CSeq: 817961235 SUBSCRIBE > > Event: presence > > Expires: 600 > > Accept: application/pidf+xml, application/xpidf+xml > > Allow-Events: presence, refer > > User-Agent: PJSIP-TEST > > Route: <sip:178.3.16.170:5060> > > Content-Length: 0 > > > > Response by presence server > > > > Status-Line: SIP/2.0 202 OK > > Message Header > > Call-ID: c1103045184c4e088b6f9c96ceefff24 > > Contact: <sip:localhost:5065> > > CSeq: 817961235 SUBSCRIBE > > From: <sip:bob at something.net>;tag=b92c03ec9bfc4a5a882d99bdb71b7a3f > > Record-Route: <sip:178.3.16.170:5060;lr> > > To: <sip:alice at something.net>;tag=a.1043.1188824974.70 > > Via: SIP/2.0/UDP > 178.3.3.34:5070;received=178.3.3.34;rport=5070;branch=z9hG4bKPj0dd2f0bdaa84483dae84722717995f44 > > Expires: 600 > > Server: OpenSER (1.3.0-dev10-notls (i386/linux)) > > P-Charging-Vector: icid-value="IMS1-3-11889172739022312270" > > Content-Length: 0 > > > > Other requests > > > > Request-Line: SUBSCRIBE sip:localhost:5065 SIP/2.0 > > Message Header > > Via: SIP/2.0/UDP > 178.3.3.34:5070;rport;branch=z9hG4bKPj1542ddcfdd4d48a2afd2c5b748d5e6d4 > > Max-Forwards: 70 > > From: sip:bob at something.net;tag=b92c03ec9bfc4a5a882d99bdb71b7a3f > > To: sip:alice at something.net;tag=a.1043.1188824974.70 > > Contact: <sip:bob at 178.3.3.34:5070;transport=UDP> > > Call-ID: c1103045184c4e088b6f9c96ceefff24 > > CSeq: 817961236 SUBSCRIBE > > Route: <sip:178.3.16.170:5060;lr> > > Event: presence > > Expires: 0 > > Accept: application/pidf+xml, application/xpidf+xml > > Allow-Events: presence, refer > > User-Agent: PJSIP-TEST > > Content-Length: 0 > > > > > > Thanks a lot for your support. > > > > Frederic.
