The server should follow RFC 3261 section 18.2.2. Based upon what you provided (assuming no maddr or connection issues), the UAS should add and use the received address. It sounds like the UAS didn't add the received parameter for use with the evaluation. _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
