Patent ID: 7197567

Claim:
A device comprising: a network interface for coupling a network device using a second packet signaling protocol to a network using a first packet signaling protocol; and a processor coupled with the network interface, in which the processor is adapted to receive and analyze a message to initiate communications from the network device using the second packet signaling protocol with the network using the first packet signaling protocol; convert the message received in the second packet signaling protocol to a message in the first packet signaling protocol; transmit the message converted to the first packet signaling protocol to a network gatekeeper; receive a response message in the first packet signaling protocol responsive to the message converted to the first packet signaling protocol and transmitted to the network gatekeeper; decode from the response message received in the first packet signaling protocol a primary network address corresponding to a primary network device associated with the gatekeeper; convert the response message received in the first packet signaling protocol to a reply message in the second packet signaling protocol; and send the reply message in the second packet signaling protocol that contains the primary network address.
