1. A system comprising:
- a first device,the first device having a first assigned temporary Internet Protocol (IP) session proxy destination address for a called party,an IP telephony session being between a calling party and the called party,the first device being connected between an IP telephony network and an asynchronous transfer mode (ATM) network, andthe first device to;
receive first IP traffic from the calling party, androute, to the called party, first ATM traffic that is based on the first IP traffic received from the calling party; and
a second device,the second device having a second assigned temporary Internet Protocol (IP) session proxy destination address for the calling party,the second device being connected between the IP telephony network and the ATM network, andthe second device to;
receive second IP traffic from the called party, androute, to the calling party, second ATM traffic that is based on the second IP traffic received from the called party.

Abstract
A method and system for providing quality of service in an IP telephony session between a calling party and a called party establishes a high quality of service ATM virtual circuit for the session between first and second devices, each of the devices having ATM capability and IP capability. The first and second devices provide bidirectional translation between IP media and ATM media. The system transports IP media for the session between the calling party and the first device, and between said called party and a second device. The virtual circuit transports ATM media for the session between the first and second devices. An intelligent control layer provides IP and ATM signaling to set up the session.

11. A method comprising:
-
initiating an Internet Protocol (IP) telephony session between a calling party and a called party; receiving, by a first device that is connected between an IP telephony network and an asynchronous transfer mode (ATM) network, first IP traffic from the calling party, the first device having a first assigned temporary IP session proxy destination address for the called party, routing, via the first device, first ATM traffic to the called party, the first ATM traffic being based on the first IP traffic received from the calling party; receiving, by a second device that is connected between the IP telephony network and the ATM network, second IP traffic from the called party, the second device having a second assigned temporary IP session proxy destination address for the calling party; and routing, via the second device, second ATM traffic to the calling party, the second ATM traffic being based on the second IP traffic received from the called party. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
