Media Gateway Controllers

A Media Gateway Controller (MGC) controls telephone services on a media gateway. An MGC may be internal to the media gateway or external to the media gateway. An Internal Call Controller (ICC) is an internal MGC. An External Call Controller (ECC) is an external MGC that communicates with the G250/G350 over the network.

An Avaya S8XXX server managed with Avaya Communication Manager (CM) software acts as an MGC for the Avaya G250 or Avaya G350 Media Gateway.
