System Parameters Media Gateway Automatic Recovery Rule

Last Updated : Nov 20, 2020 |

This screen defines rules for returning a fragmented network, where a number of Branch Gateways are being serviced by one or more Survivable Remote Server (Local Survivable Processors) automatically to the primary media server. The system displays a different warning message or time window grid depending on the option selected for the Migrate H.248 MG to primary field.

In the time window grid, an x or X can be specified for each hour. Leave blank to disable. This method helps with overlapping time issues between days of the week. There is no limit on intervals.

For more information on Auto Fallback for Branch Gateways, see Administering Network Connectivity on Avaya Aura® Communication Manager.

Example command: change system-parameters mg-recovery-rule n, where n is the assigned recovery rule number.
