Voice over internet protocol proxy gateway
First Claim
1. A proxy gateway comprising:
- a terminal portion, the terminal portion being configured to interface with a terminal via a network to which the terminal is connected; and
a gateway portion coexisting and in communication with the terminal portion, the gateway portion being configured to interface with a gateway and a gatekeeper,wherein the proxy gateway is configured to provide for call setup, call proceeding, and call termination,wherein the proxy gateway registers with a directory service associated with the proxy gateway and the terminal,wherein when a telephone calls a terminal, the proxy gateway is configured to prompt the directory service to look up an IP address of the called terminal, based on a telephone number of the called terminal received from the gateway, the gateway being connected to a telephone network to which the telephone is connected, the proxy gateway bridging the called terminal to the telephone network via the gateway, andwherein the proxy gateway is configured to prompt the called terminal to log onto the network so that a new IP address can be assigned to the called terminal when the directory service cannot find any IP address associated with the called terminal, the directory service being configured to provide the new IP address to the proxy gateway.

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 proxy gateway has dual characteristics such that it behaves as a terminal with respect to other terminals and as a gateway with respect to other gateways.

11. A method of establishing voice over network protocol telephony, the method comprising:
-
establishing communications between a terminal portion of a proxy gateway and a gateway portion of the proxy gateway, the proxy gateway being connected to a network, wherein the proxy gateway provides for call setup, call proceeding, and call termination; establishing an interface between a gatekeeper and the gateway portion of the proxy gateway, the gatekeeper being connected to the network; establishing an interface between a gateway and the gateway portion of the proxy gateway, the gateway being connected to the network and a telephone network; and establishing an interface between a terminal and the terminal portion of the proxy gateway, the terminal being connected to the network, the proxy gateway bridging the terminal to the telephone network via the gateway, wherein the proxy gateway registers with a directory service associated with the proxy gateway and the terminal, when a telephone calls a terminal, the proxy gateway prompts the directory service to look up an IP address of the called terminal based on a telephone number of the called terminal received from the gateway, the telephone being connected to the telephone network, the proxy gateway bridging the called terminal to the telephone network via the gateway, and wherein the proxy gateway prompts the called terminal to log onto the network so that a new IP address can be assigned to the called terminal when the directory service cannot find any IP address associated with the called terminal, the directory service provides the new IP address to the proxy gateway. - View Dependent Claims (12, 13, 14, 15)

16. A telephony system comprising:
-
a network; a terminal connected to the network; a gatekeeper connected to the network; a gateway connected to the network and a telephone network; and a proxy gateway connected to the network, the proxy gateway communicating with the terminal and the gateway via the network, the proxy gateway comprising a gateway portion and a terminal portion, the proxy gateway providing for call setup, call proceeding, and call termination, wherein the proxy gateway behaves as a terminal with respect to the terminal and behaves as a gateway with respect to the gateway; wherein the proxy gateway registers with a directory service associated with the proxy gateway and the terminal, when a telephone calls a terminal, the proxy gateway prompts the directory service to look up an IP address of the called terminal based on a telephone number of the called terminal received from the gateway, the telephone being connected to the telephone network, the proxy gateway bridging the called terminal to the telephone network via the gateway, and wherein the proxy gateway prompts the called terminal to log onto the network so that a new IP address can be assigned to the called terminal when the directory service cannot find any IP address associated with the called terminal, the directory service provides the new IP address to the proxy gateway. - View Dependent Claims (17)
