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.

21. A system for providing a quality of service IP telephony session between a calling party and a called party, the system comprising:
-
a first device, having an assigned temporary IP session proxy destination address for the called party, connected between an IP telephony network and an asynchronous transfer mode (ATM) network, the first device to receive IP traffic from the calling party and to route, to the called party, ATM traffic that is based on the IP traffic received from the calling party; and a second device, having an assigned temporary IP session proxy destination address for the calling party, connected between the IP telephony network and the ATM network, the second device to receive IP traffic from the called party and to route to the calling party, ATM traffic that is based on the IP traffic received from the calling party. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A method comprising:
-
initiating an IP telephony session between a calling party and a called party; receiving, at a first device connected between an IP telephony network and an asynchronous transfer mode (ATM) network, IP traffic from the calling party, the first device having an assigned temporary IP session proxy destination address for the called party, routing, via the first device, ATM traffic to the called party, where the ATM traffic to the called party is based on the IP traffic received from the calling party; and receiving, at a second device connected between the IP telephony network and the ATM network, IP traffic from the called party, the second device having an assigned temporary IP session proxy destination address for the calling party; and routing, via the second device, ATM traffic to the calling party, where the ATM traffic to the calling party is based on the IP traffic received from the called party. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40)
