The enable mg-return command overrides the gateway recovery rules that block registration if Survivable Remote Servers are active or inactive. Such overriding can be applied per region.
If there are no gateways in the region and the command enable mg-return network-region R is run, the following error message is shown:
IP network region has no gateways administered.
The administrator can run the command disable nr-registration on any region. If the status of a gateway in that region is already ad or ap, the status changes to rd. For information on the gateway registration statuses — ad, ap, and rd — see the field descriptions of display media-gateway, list media-gateway, and status media-gateway.
Important:
The enable mg-return command remains active for a period of 60 minutes. During this period of 60 minutes, if you want to move the gateways and phones from server to server, you must run the disable mg-return command first to end the 60 minutes timer. If you do not run the disable mg-return command, the timer either ends itself after a period of 60 minutes or after the Survivable Remote Server reports to the main Communication Manager server that the gateways have unregistered from the Survivable Remote Server.
