● You can configure the Avaya CM to support the auto fallback feature, which enables a
G450 being serviced by an LSP to return to its primary MGC automatically when the
connection is restored between the G450 and the MGC. When the G450 is being served
by its LSP, it automatically attempts to register with its MGC at periodic intervals. The MGC
can deny registration in cases in which it is overwhelmed with call processing, or in other
configurable circumstances. By migrating the G450 to the MGC automatically, a
fragmented network can be unified more quickly, without the need for human intervention.
Note:
Note: Auto fallback does not include survivability. Therefore, there is a short period
during registration with the MGC during which calls are dropped and service is
not available. This problem can be minimized using the connection preserving
migration feature.
● The G450 features a dynamic trap manager, which enables you to ensure that the G450
sends traps directly to the currently active MGC. If the MGC fails, the dynamic trap
manager ensures that traps are sent to the backup MGC.
MGC management
The MGC is managed by the Avaya Communication Manager (CM). The G450 supports Avaya
Communication Manager (CM) release 5.0.
