Abstract
A method and apparatus for establishing a communication session in an IMS Centralized Services communication network. A Service Centralization and Continuity Application Server (SCC AS) receives a request from an originating device to establish a session with a target device. The request includes a plurality of codec identifiers that could be used by the originating device. The SCC AS sends a second request to establish the session to the target device. The SCC AS subsequently receives, from an intermediate node between the SCC AS and the target device, an invite message. The invite message includes an indication that a codec identifier has been selected from the plurality of codec identifiers. The SCC AS then sends a message to the intermediate node instructing the intermediate node to establish the session.
