If you are using a Event Dialog presence agent (i.e: pua_dialoginfo) you don't need forwarding SUBSCRIBE (Event: dialog) to UAS. > if so, > how do they differ from normal ones where presence server is used? It depends on your environment. If you use Dialgo presence implemented in the proxy then you need a presence agent (who sends the NOTIFY to subscribers about calls from/to an AoR). Also you have a presence server that will receive the SUBSCRIBE (Event: dialog). You could use this scenario with the current draft. Just one important issue: I suppose you don't allow anyone subscribing to calls status of any local users, but in the case of this draft you should allow any SUBSCRIBE with: Event: dialog;call-id=xxxx;to-tag=xxxx Expires: 0 Note this subscription only involves an specific dialog. If B knows these dialog parameters it means that he is the receptor and he is trying to verify the sender AoR (From). In this case your presence server should allow that SUBSCRIBE (or your proxy should allow that SUBSCRIBE being forwarded to UAS if you don't use a dialog presence server). -- 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
