As part of CDIV, a (SIP) Event Notification Framework-based mechanism is used for notifying Users about diversions (re-directions or forwarding) of their incoming communication sessions. A new event package is proposed for allowing users to subscribe for and receive such notifications. Users have further capability to define filters controlling the selection, rate and content of such notifications. This SIP event package is applicable to the IMS and may not be applicable to the general Internet.}, }
