Abstract: A network device including a plurality of communication interfaces, including a telephone line interface, a computer data interface, and a broadband network interface; a processor; a machine-readable storage medium which during use stores a call processing application and service profiles, and which stores executable instructions to mediate communications between the plurality of communication interfaces, the instructions causing the network device to detect network signaling events or trigger points in a telephone call and invoke the call processing application in response to the detected network signaling events or trigger points, the call processing application operating according to parameters defined in the service profiles.

Abstract: An apparatus and method achieve a level of telephony application functionality commensurate with TDM (Time Division Multiplex) device interfaces used in legacy PSTN (Public Switched Telephone Network) voice and facsimile telephony applications. The apparatus and method rely upon the architectural model embraced by VOP (Voice Over Packet) carrier network network standards, and include network elements and a protocol framework. The apparatus and method build upon the SIP model to incorporate essential telephony application functions previously only available using a PSTN infrastructure. The telephony service interface incorporates mechanisms for both call control and media control operations.
