Recommendation ITU-T H.248.83 defines functionality that allows a media gateway (MG) to indicate to a media gateway controller (MGC) what media gateway instance is in use. A media gateway instance relates to a named set of configuration parameters associated with a media gateway (or virtual media gateway). These configuration parameters may relate to (but are not limited to) the provisioned values associated with ITU-T H.248 packages, allocated memory, allocated storage and allocated processing resources, etc.
