The fight over subscriptions can be just as bad (i.e. subscription recreation loop). More specifically if the server doesn't allow an unlimited number of simultaneous subscriptions for a particular event package, it will need to decide what to do. If the server terminates an old subscription because allowing a new subscription, the device owning the old subscription might create another subscription, again, again, ... if NOTIFY sent when terminating the subscription. _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
