Abstract: A method and apparatus comprises a controller to establish a call session between a first endpoint and a second endpoint. Without exchanging call setup signaling with the first endpoint, the controller is able to pivot the call session from the second endpoint to another endpoint so that media communication can occur between the first and other endpoints. The first endpoint remains "anchored" in the call session. The pivot is accomplished by sending a call request to the other endpoint and exchanging messages with a media portal (44, 45) that controls the communication of packets between endpoints. The media portal (44, 45) contains a network address and translation module that performs translation of addresses and/or ports of media packets communicated from one endpoint to another.

Abstract: A method and apparatus for communicating data units (e.g., Internet Protocol or IP packets) between devices (22, 24, 36, 49) on one or more networks includes storing address and/or port translation information, and receiving a data unit having a source address and port and a destination address and port. Both the source and destination addresses and/or ports are translated, with the data unit containing the translated source and destination addresses and/or ports transmitted to a destination.
