Dear all, I am reading draft-ietf-simple-presence-03 (SIP Extensions for Presence), it does not specify what the subscriber should do when the SUBSCRIBE fail. I am not sure whether the subscriber should keep sending SUBSCRIBE at some refresh interval if the previous SUBSCRIBE is timeout or get a 404, or it should just terminate the session.
Regarding the following scenario: if somebody maintains a buddy-list, when he starts his UA, the UA can send SUBSCRIBE to each buddy to get current presence information of the buddy. If one buddy is not online, then the SUBSCRIBE will timeout or it will get a 404 from the proxy server. If the UA does not re-send SUBSCRIBE, it will not be aware when the buddy is online after some time. If the proxy server is a presence server, this will not be a problem. But if there isn't any presence server, what should the subscriber do? -Lu Wei _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
