That's not true. - A calls B - Inmediatelly B sends a SUBSCRIBE (Event: dialog;call-id=xxx;to-tag=xxx) to A AoR (which could fork). - The A contact in this dialog will reply 200 OK for the SUBSCRIBE. - B already nows that the sender is verified and sends the 180 Ringig for the INVITE... - A also sends a NOTIFY as is mandatory for presence (but this is not important and A doesn't require to receive it). No PUBLISH is needed. PUBLISH appears when subscribing to an AoR calls without specifyng "call-id" and "to-tag" parameters. Please, review the draft flows ;) -- 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
