It turns out to be useful if you are trying to accumulate "busy" status information for an AoR. In theory, you can just send a dialog event SUBSCRIBE to the AoR, but that tends to get forked to the voicemail server, etc. What you really want to do is subscribe to reg events for the AoR, and then do individual dialog event subscriptions to every contact for the AoR. That way, you're talking directly to each line-appearance of the AoR. And if you can get a GRUU for a contact, you subscribe using the GRUU rather than the stated contact URI, because that is more likely to avoid NAT problems, etc. Dale _______________________________________________ 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
