If you are licensed for one instance of IVR Routing only and the IVR Routing Remote Server ports go offline, the Enterprise Server remains available as a backup. In this case, you must re-assign ports from the offline IVR Routing Remote Server back to the Enterprise Server.
If you disabled MiContact Center Inbound Router Service, MiContact Center Outbound Router Service, and MiContact Center UPiQ Service, you must re-enable them before assigning ports from the Remote Server back to the Enterprise Server.
You can select multiple ports by holding the Shift key.
The ports are assigned back to the Enterprise Server.
