Methods and Apparatus for Forwarding IP Calls Through A Proxy Interface
First Claim
1. An apparatus, comprising:
- a session controller configured to be coupled to a communications network, the session controller 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, the session controller being further configured to receive a signaling message from the endpoint at a second time later than the first time, the session controller being further configured to forward an indication of the VoIP registration request and the signaling message to an application server, the session controller being further configured to forward an indication of the VoIP registration request and the signaling message such that at least a portion of the topology of the communications network beyond the session controller is hidden to the endpoint.

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.

6. A method, comprising:
-
receiving at a session controller coupled to a communications network an indication of a Voice over Internet Protocol (VoIP) registration request at a first time from an endpoint having a third-party registration;
receiving at the session controller a signaling message from the endpoint at a second time later than the first time; and
forwarding to an application server an indication of the VoIP registration request and the signaling message, the forwarding an indication of the VoIP registration request and the signaling message being performed such that at least a portion of the topology of the communications network beyond the session controller is hidden to the endpoint. - View Dependent Claims (7, 8, 9, 10)

11. A computer program stored on a computer-readable medium, the computer program comprising:
-
a first receiving instruction to receive at a session controller coupled to a communications network an indication of a VoIP registration request from an endpoint at a first time, the endpoint having a third-party registration;
a second receiving instruction to receive at the session controller a signaling message from the endpoint at a second time later than the first time; and
a forwarding instruction to transparently forward an indication of the VoIP registration request and the 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. - View Dependent Claims (12, 13, 14, 15)
