SYSTEM AND METHOD FOR USING MULTIPLE COMMUNICATION PROTOCOLSIN MEMORY LIMITED PROCESSORS

摘要

A system and method for implementing large and/or multiple telecommunication protocols utilizing memory-limited processors. Telecommunication protocols a re expressed as virtual machine instructions defining a finite state machine. A telecommunication protocol engine (100) implements the telecommunication protocols using a virtual machine (125) operating under the control of a CPU (120). A telephony gateway (600) comprising a telecommunication protocol engine (610, 650, 640) interfaces with a communication device and a packet switched network. A network of telephony gateways (720, 730) communicating with a provider gateway (703, 705) facilitates communication over a packet switched network. A call placed by a calling telephony gateway to receiving device on the same network or another network is routed according to a prefi x in a telephone code sent by the calling telephony gateway.
