Supported Media Servers - Avaya G250 Overview

Supported media servers

The MGCs supported by the Branch Gateway include both ECCs and ICCs. Both the G250 and
the G350 support the following MGCs:

The Branch Gateway provides the following configuration options to help you ensure
continuous telephone services:
You can configure the Branch Gateway to use up to four media servers. If the MGC is an
●
S8700, S8710, or S8720, the first server on the list will normally be the primary C-LAN
board connected to the media server. If the MGC is an S8400 or S8500, the first server on
the list will be either the primary C-LAN board connected to the media server or an
Ethernet port on the server that has been enabled for processor Ethernet connections. If
the MGC is an S8300, the first server on the list will be the IP address of the S8300. The
remaining servers will be alternate C-LAN boards connected to the media server (S8400,
S8500, or S8700-series media servers), an S8300 configured as an LSP, or the port
enabled as the Ethernet processor port on an S8500 configured as an LSP.
Using the connection preserving migration feature, you can configure the Branch Gateway
●
to preserve the bearer paths of stable calls in the event that the Branch Gateway migrates
to another MGC (including an LSP), including migration back from an LSP to the primary
MGC. A call for which the talk path between parties in the call has been established is
considered stable. A call consisting of a user listening to announcements or music is not
considered stable and is not preserved. Any change of state in the call prevents the call
from being preserved. For example, putting a call on hold during MGC migration will cause
the call to be dropped. Special features, such as conference and transfer, are not available
on preserved calls. Connection preserving migration preserves all types of bearer
connects except BRI. PRI trunk connections are preserved.
