Abstract

A proxy gateway for voice over Internet protocol telephony. The proxy gateway includes a terminal portion and a gateway portion. The gateway portion is coexisting and in communications with the terminal portion. The proxy gateway is capable of interfacing with a gatekeeper and a gateway. The proxy gateway is further capable of interfacing with at least one terminal via a network to which the at least one terminal is attached. The proxy gateway uses its terminal portion for interfacing with the at least one terminal. The proxy gateway uses its gateway portion for interfacing with the gateway and gatekeeper. Another aspect of the invention is a telephony system in which at least one proxy gateway is deployed. The telephony system includes a network and at least one terminal attached to the network. The telephony system additionally includes a gatekeeper and a gateway communicating with the gatekeeper and interfacing between a telephone network and, via the network, the at least one terminal. The telephony system further includes the proxy gateway. The proxy gateway communicates with the gatekeeper, the at least one terminal and the gateway. The proxy gateway has dual characteristics manifested by a gateway portion and a terminal portion so that with respect to the at least one terminal the proxy gateway behaves as a terminal and so that with respect to the gateway the proxy gate behaves as a gateway.
