Hi , I have a question on a specific behavior seen with a Proxy, the behavior is as follows.
UAC Proxy |---Invite(req-URI:A, callid:1, Ftag=1)----->| | | |<----Invite(URI:B, callid:1,ftag=2)---------| And the Proxy Record-Routes as well retaining the Original Contact. In this specific case the UAC on seeing a call-id which it generated with a different From Tag is failing the Invite Request. Question is whether it is a correct behavior on the Proxy to change the >From Tag retaining the same call-id in the above case. I would also like opinion on what shld be the behavior of UAC in this case. The UAC is assuming that Call-id is globally unique and is able to detect that this call-id belongs to itself and since the From tag is not matching with what it generated it is failing the request.
