Abstract
Disclosed are methods and apparatus for translating data within a cable network between a first voice-over-IP (VOIP) protocol used by a user agent and a second VOIP protocol used by a call management server, or other type of call receiver. In one embodiment, data from an SIP (Session Initiation Protocol) user agent is translated for an NCS (Network Call Signaling) call management server. In one implementation, translation mechanisms are provided within the customer premises equipment in which the respective user agent is also configured.
