Abstract:
1. A Session Initiation Protocol (SIP) gateway, comprising: a trunk service unit configured to provide session initiation protocol (SIP) service to at least one subscriber equipment in a subscriber network, each subscriber equipment having an associated subscriber equipment identifier, the trunk service unit providing subscriber-facing signaling to communicate with the subscriber network and network-facing signaling to communicate with a stimulus-based network; and a plurality of logical multimedia terminal adapters (L-MTA), each in communication with the trunk service unit and having a logical interface implemented with general purpose hardware and programmable code for exchanging messages with an external logical object to emulate signals, the plurality of L-MTAs associated with the stimulus based network and configured to obtain service from a call management server (CMS) in the stimulus-based network, each L-MTA having an associated L-MTA equipment identifier, the network-facing signaling of the trunk service unit being used to control the plurality of L-MTAs, wherein a communication session is created with the subscriber equipment and the CMS as participants when the subscriber equipment is mapped to an associated L-MTA, and wherein once the communication session is established media data is enabled to pass directly from the subscriber equipment to a media termination point in the stimulus network.
