If your account is set up to manage user access by Business Unit or Location, you may need to assign a Bell Controller Relay to its applicable business unit or location. By default, a relay is assigned to the account business unit and is not assigned to a location.
Go to Devices > Bell Controller Relays.
Select the Name link of the relay.
Select Show Advanced Options.
Set the assigned Business Unit and/or Location.
From the Business Unit drop-down list, select a Business Unit.
From the Location drop-down list, select a Location.
