RFC 3265 section 3.2.2 indicates that a NOTIFY MUST be sent. It is an abnormal situation if the NOTIFY is not sent. It is up to each vendor to decide how best to handle the abnormal situation for the given event package. Concerning desire to give up prior to 200 responses Expires value, the sending of SUBSCRIBE to terminate the subscription is only helpful for the notifier if the notifier does not follow the MUST and SHOULD text of section 3.2.2. _______________________________________________ Sip-implementors mailing list [email protected] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
