SYSTEM AND METHOD FOR MANAGING INTEROPERABILITY OF INTERNET TELEPHONY NETWORKS AND LEGACY TELEPHONY NETWORKS
First Claim
1. A method for providing a secure out of band signaling service to control use of wideband communications networks, comprising:
- receiving a signaling origination message from an originating telephony endpoint, the signaling origination message including an identifier uniquely representing the originating telephony endpoint in an out of band signaling network;
identifying a terminating telephony endpoint from the signaling origination message, the terminating telephony endpoint associated with an identifier uniquely representing the terminating telephony endpoint in the out of band signaling network;
establishing a call session between the originating telephony endpoint and the terminating telephony endpoint, the call session defining a use of a wideband communications network; and
providing identity control over the use of the wideband communications network based on the identifiers uniquely representing the originating telephony endpoint and the terminating telephony endpoint in the out of band signaling network.

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.
