- Abstract:
In this paper, we introduce a new architecture that can be used
for offering Internet Telephony service to residential customers. The architecture proposed
addresses scalability and availability requirements of mass-market deployment of
carrier-grade services and supports interconnection with SS7 for Internet Telephony calls
to the Public Switched Telephone Network (PSTN). The architecture is based on the concept
of a gateway decomposition that separates the media transformation function of today’s
H.323 gateways from the gateway control function of the gateways and centralizes the
intelligence in a call agent. Media Gateway Control Protocol (MGCP) is introduced as the
protocol between the call agent that assumes the gateway control function and the gateway
that provides just the media transformation function. Interworking of the architecture and
the PSTN, Session Initiation Protocol (SIP) and H.323 are also discussed.
