METHOD AND SYSTEM FOR PROVIDING INTERDOMAIN TRAVERSAL IN SUPPORT OF PACKETIZED VOICE TRANSMISSIONS
First Claim
1. A method for providing communication services, the method comprising:
- receiving a request for establishing a voice call from a source endpoint behind a first network address translator of a first domain, wherein the request specifies a directory number of a destination endpoint within a second domain;
selectively determining a network address for communicating with the destination endpoint based on the directory number;
determining existence of a second network address translator within the second domain; and
if the network address can be determined, establishing a media path between the source endpoint and the destination endpoint based on the network address to support the voice call.

Abstract
An approach provides interdomain traversal to support packetized voice transmissions. A request for establishing a voice call is received from a source endpoint behind a first network address translator of a first domain, wherein the request specifies a directory number of a destination endpoint within a second domain. A network address is determined for communicating with the destination endpoint based on the directory number. Additionally, existence of a second network address translator within the second domain is determined. If the network address can be determined, a media path is established between the source endpoint and the destination endpoint based on the network address to support the voice call.
