Hi All, As per Rfc 3265, ------------------------------------------------------------------------- A subscription is destroyed when a notifier sends a NOTIFY request with a "Subscription-State" of "terminated". A subscriber may send a SUBSCRIBE request with an "Expires" header of 0 in order to trigger the sending of such a NOTIFY request; however, for the purposes of subscription and dialog lifetime, the subscription is not considered terminated until the NOTIFY with a "Subscription-State" of "terminated" is sent. -------------------------------------------------------------------------
Case I: After an Unsubscribe (Expires=0) Request, if the Subscriber does not receive a NOTIFY with a "Subscription-State" of "terminated", when will the subscription be removed. Is there any specific Timeout period, after which the Subscriber himself removes the Subscription.. Case II: The same holds good for Subscription Poll Requests, if the NOTIFY were not to be received, when will the Subscription be removed at Subscriber end. Additionally, if the NOTIFY was received with a "Subscription-State" of "active" in either of the above cases, how should the Subscriber behave?? Thankz in advance.....
