That's not totally accurate, methinks. It requires support for the dialog-event package on the UAC, and requires the UAC to allow some random far-end UA outside its domain that it does not know about to subscribe to it. [And it requires the path between the UAC and UAS to not contain b2bua's that change call-id or tag, of course] The set of deployed devices/paths which satisfy those requirements is not the universe, but then again it's not the null set either. ;) -hadriel _______________________________________________ Sip mailing list https://www.ietf.org/mailman/listinfo/sip This list is for NEW development of the core SIP Protocol Use [EMAIL PROTECTED] for questions on current sip Use [EMAIL PROTECTED] for new developments on the application of sip
