SYSTEM AND METHOD FOR MANAGING INTEROPERABILITY OF INTERNET TELEPHONY NETWORKS AND LEGACY TELEPHONY NETWORKS
First Claim
1. A method for establishing peer-to-peer communications through secure out of band signaling, comprising:
- receiving a message requesting content from a destination at a signaling device, wherein the message identifies an Internet address for the destination and a local area network address for a user terminal that initiated the request;
communicating a query to a signaling network to establish communications between the user terminal and the destination, wherein the signaling device receives a response to the query that enumerates one or more nodes, the enumerated nodes operable to proxy the message to the Internet destination on behalf of the user terminal;
establishing one or more Network Address Translation flows for the proxied message at an Internet router, wherein the Network Address Translation flows instruct the Internet router to accept incoming data from the one or more enumerated nodes, and to forward the incoming data to a local area network address for the signaling device;
receiving the requested content at the signaling device, wherein the enumerated nodes provide the requested content to the Internet router through at least one Internet service provider network, the Internet router operable to forward the requested content to the signaling device using the established Network Address Translation flows; and
providing the received content from the signaling device to the user terminal.

Abstract
A system and method for providing interoperability between Internet telephony networks and legacy telephony networks includes conveying an address of an Internet telephony endpoint in a legacy telephony protocol. A globally unique Uniform Resource Identifier, referred to as a Universal Global Title, may be assigned as the address of the Internet telephony endpoint. The URI-based address of the Internet telephony endpoint can be conveyed to a legacy telephony network as an Internet Address Parameter, implemented as an extension to the ANSI ISDN User Part legacy telephony protocol. As such, a Universal Teletraffic EXchange may be provided where Internet telephony networks and legacy telephony networks can exchange addressing and signaling information while interoperating at a peer-to-peer level.
