Abstract

A session controller configured to be coupled to a communications network is disclosed. The session controller is configured to receive an indication of a Voice over Internet Protocol (VoIP) registration request at a first time from an endpoint having a third-party registration, and to receive a signaling message from the endpoint at a second time later than the first time. The session controller is further configured to forward an indication of the VoIP registration request and a signaling message to an application server, such that at least a portion of the topology of the communications network beyond the session controller is hidden to the endpoint.
