If the 200 OK response for the INVITE sent is as you described, the ACK/BYE should have
Request URI as: sip:pu1 at P1.com:5060 and Route headers as: Route: <sip:pu2 at P2.com:5060;lr> Route: <sip:pu3 at P3.com:5060;lr> Route: <sip:u at UA.com:5060> Refer to RFC 3261, Section "12.2.1.1 Generating the Request" under UAC Behavior.

Is it possible to follow strict routing even though I get lr param? While I was interoperating with sipgate.de (SIP express router) I got ftag param and lr param in 200 OK, I was trying to send ACK/BYE requests to record-route URI instead of final destination. Iam not getting any response for BYE. Please help me. regards, SIPIT --------------------------------- Do you Yahoo!? Yahoo!
