The Media Gateway Controller (MGC)

The Media Gateway Controller (MGC) controls telephone services on the Avaya G350 Media Gateway.
You can use a media server with Avaya Communication Manager software as an MGC. The G350
supports both External Call Controllers (ECC) and Internal Call Controllers (ICC). An ICC is an Avaya
S8300 Media Server that you install in the G350 as a media module. An ECC is an external media server
that communicates with the G350 over the network.
NOTE:
When the G350 uses an ECC, it can use a local S8300 as a backup controller. The S8300
functions in Local Survivable Processor (LSP) mode. If the ECC stops serving the G350,
the S8300 takes over the service.

To register the G350 with an MGC, you need the G350's serial number. You can find this serial number in
one of the following ways:
•
Use the

Look for a 12-character string located on a label on the back panel of the G350.

Configuring the MGC list

The G350 must be registered with an MGC in order to provide telephone service. Use the
command to set the G350's MGC. You can enter the IP addresses of up to four MGCs with the
command. The first MGC on the list is the primary MGC. The Avaya G350 Media Gateway searches
list
for the primary MGC first. If it cannot connect to the primary MGC, it searches for the other MGCs on
the list.
NOTE:
To register an S8500 or S8700 media server as the MGC, use the IP address of the media
server's Control-LAN card (CLAN) rather than the IP address of the media server itself.
The following is an example of the
G350-001> set mgc list 132.236.73.2, 132.236.73.3, 132.236,73.4, 132.236.73.5
If the media server with the IP address 132.236.73.2 is available, that media server becomes the G350's
MGC. If that server is not available, the G350 searches for the next media server on the list, and so on.
