1. A method for implementing transcoder-free operation in a media gateway, the method comprising:

  • (a) receiving first and second lists of media encoding rates and corresponding indices used by first and second media endpoints of a media stream connection;

    (b) determining whether transcoder-free operation is possible for the media stream connection based on the first and second lists; and

    (c) in response to determining that transcoder-free operation is possible for the media stream connection, establishing a transcoder-free connection in the media gateway between the first and second endpoints using a single digital signal processor (DSP) to monitor and map between indices and encoding rates used by the first and second endpoints during the media stream connection.
