Use enable nr-registration to end an active disable nr-registration command.

This enables the gateways and IP-phones within the specified IP Network Region to register with the primary server or survivable processor.

However, the enable nr-registration command can only end an active disable nr-registration command. This command cannot override any other condition that prevents the gateways and IP phones to register with the primary server or survivable processor.

For example, if the time-day-window prevents the gateways and IP phones to register with the primary server, you cannot use the enable nr-registration command to register the gateways and IP phones with the primary server.

If you have set the value for the Force Phones and Gateways to Active LSPs? field in the system-parameters ip-options screen as y and then run the enable nr-registration command when the Survivable Remote Server is active, the command does not immediately enable the network region. Instead, the enable nr-registration command puts the network region into an auto-disabled state. Communication Manager does this so that if the Survivable Remote Server is backing up more than one region, the enable nr-registration command does not cause a split registration by allowing endpoints in that one region to return to the Communication Manager server while endpoints in other regions backed up by the same Survivable Remote Server stay on the Survivable Remote Server.

Use enable nr-registration on a primary server, a Survivable Core Server, and a Survivable Remote Server. The enabled network region registration state on the primary server is not file-synced to the Survivable Remote Server or associated Survivable Core Server.
