Enter disable nr-registration network-region so that gateways and IP phones in the specified network region will register to a Survivable Remote Server. The registration of the IP network endpoints to a server is being disabled, not the IP network region itself. The use of this command is a temporary recovery action, not a corrective action.

After the network problem has been corrected, enter enable nr-registration network-region to enable registration of the IP network endpoints to a server. This will allow them to re-register with the main server depending upon the administered recovery rule specified on the change media-gateway screen.
