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.
