The Media Gateway Controller (MGC)

The Media Gateway Controller (MGC) controls telephone services on the Avaya G250/G350
Media Gateway. You can use a media server with Avaya Communication Manager software as
an MGC. The G250/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 G250/G350 as
a media module. An ECC is an external media server that communicates with the G250/G350
over the network.
When the G250/G350 uses an ECC, it can use a local S8300 as a backup controller for
Enhanced Local Survivability (ELS). The S8300 functions in Local Survivable Processor (LSP)
mode. If the ECC stops serving the G250/G350, the S8300 takes over the service. For
information on Standard Local Survivability (SLS) and other backup features, see
and migration options
Table 2 lists the media servers that can be used with the G250/G350.

To register the G250/G350 with an MGC, you need the G250/G350's serial number. You can
find this serial number in one of the following ways:
Use the show system command

Look for a 12-character string located on a label on the back panel of the G250/G350
