System and method for providing caller ID service in a multi-region cable network

摘要

A system and method for providing caller ID in a multi-region cable network. Caller identifying (CID) information of an incoming VoIP call is provided to a digital telephone subscriber through a video termination device (VTD) using a path that is different from the path by which the VoIP call packets are delivered to the digital telephone subscriber. The telephone number of a digital telephone subscriber is associated with the IP address and/or MAC address of the subscriber's VTD. The called number of the incoming VoIP call is used to select the VTD to which the CID information is delivered. A message is then sent through an out-of-band channel to the digital telephone subscriber's VTD comprising the CID information for display on video display equipment. Alternatively, the VTD is DOCSIS-compliant and a message is addressed to the VTD using the IP address of the VTD DOCSIS modem.
