PROBLEM TO BE SOLVED: To provide backhauling layers for multiple protocols from a media gateway to a media gateway controller. SOLUTION: For media gateways (10) supporting access networks (16) using multiple protocols, the upper level call processing layer of each of the multiple protocols is backhauled to the media gateway controller (12). In the messages sent from the media gateway (10) to the media gateway controller (12), the particular protocol being used is identified. As such, the media gateway (10) informs the media gateway controller (12) of a proper protocol used in association with call processing messages.
