A Media Gateway Controller (MGC) is a media server (call controller) that controls telephone services on the TGM550. An Avaya media server running Avaya Communication Manager (CM) software acts as an MGC for the TGM550.
The following media servers running Avaya Communication Manager can be used as an MGC with the TGM550:
To provide telephony services, the TGM550 must be registered with at least one Media Gateway Controller (MGC). You can configure the IP addresses of up to four MGCs that the TGM550 can connect to in the event of a link failure. The MGC list consists of the IP addresses of the MGCs to connect to and the order in which to reestablish the H.248 link. The first MGC on the list is the primary MGC. The TGM550 searches for the primary MGC first. If it cannot connect to the primary MGC or loses its connection to the primary MGC, it attempts to connect to the next MGC in the list, and so on.

You must also administer Avaya Communication Manager on the configured Media Gateway Controllers to support the TGM550. For more information, see the following Avaya IG550 Integrated Gateway manuals at http://support.avaya.com:
