Abstract: A method, system and apparatus for announcing caller information to users over a television link. The method comprises receiving signalling information associated with an incoming call destined for a destination party, the signalling information comprising a portion conveying information regarding an origin of the incoming call and information regarding an identity of the destination party. The method also comprises attempting to establish a telephony link with a device associated with the destination party over a communication network in response to said receiving. The method further comprises attempting to establish a second telephony link with a processing entity to convey said portion of the signalling information to the processing entity to cause delivery of an indication of the origin of the incoming call over a television link associated with the destination party, said indication based on said information regarding an origin of the incoming call.

Abstract: A method, system and apparatus for announcing caller information to users over a television link. The method comprises receiving, via a portion of a data network adapted for handling Voice-over-IP (VoIP) calls, Session Initiation Protocol (SIP) signalling information associated with an incoming call destined for a destination party, the SIP signalling information comprising a portion conveying information regarding an origin of the incoming call and information regarding an identity of the destination party. The method further comprises attempting to establish a telephony link with a device associated with the destination party over a communication network in response to the receiving. The method further comprises releasing the portion of the SIP signalling information to a processing entity to cause delivery of an indication of the origin of the incoming call over a television link associated with the destination party, the indication based on the information regarding an origin of the incoming call.
