A note more about it: In RFC 3261 the Contact is optional in 101-199 since those responses don't always create a dialog (just if there is Contact header). But RFC 3262 says that the reponse must establish a dialog (if not yet created) so it required it has Contact. Otherwise the dialog is not completed. -- Iñaki Baz Castillo _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
