> Is 180 response received without TO tag a forked response? A 18x without To tag is non compliant; see rfc3261 section 8.2.6.2. Thus the UAC has to decide how it wants handle the abnormal situation.
RFC 2543 did not always require tags to form dialogs; however RFC 3261 does. Thus various vendors likely handle the abnormal situation differently. _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
