ABSTRACT:
A wireless device may connect to a telecommunications network and register with a Session Initiation Protocol server. The Session Initiation Protocol server may notify a network element on the telecommunications network of the wireless device's registration. In response to a disconnection of the wireless device from the telecommunications network, the network element may notify the Session Initiation Protocol server of the wireless device's disconnection. The Session Initiation Protocol server may then responsively deregister the wireless device.
