Abstract
A tunneling address translation engine enables a Internet protocol packet audio conversation to be maintained between two device. At least one of the devices may be behind a firewall or behind a network address translator, or proxy server. The tunneling address translation engine routes frames of audio data to an intended destination utilizing unreliable data protocols which do not include source address information. An audio conversation may be maintained through a sequence of tunneling address translation engines.
