I agree, imagine if you sends such a SUBSCRIBE but as refresh SUBSCRIBE (in-dialog request), and you get 481. What does it mean?: a) The current SUBSCRIBE dialog doesn't exist anymore. b) The indicated dialog in the "Event: dialog;call_id=xxx,to_tag=xxx" doesn't exist. ? -- Iñaki Baz Castillo <[email protected]> _______________________________________________ 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
