The Remove-UMDialplan cmdlet deletes an existing Unified Messaging (UM) dial plan.

Remove-UMDialPlan -Identity <UMDialPlanIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

The Remove-UMDialplan cmdlet is used to delete an existing UM dial plan from the Active Directory directory service. The administrator must make sure that the UM dial plan is not being used by other UM objects such as UM mailbox policies or UM IP gateways. When you delete an existing UM dial plan, the cmdlet verifies that the specified UM dial plan is not referenced by a Unified Messaging server, UM IP gateway, or UM mailbox policies. The only benefit gained from deleting an obsolete UM dial plan is to reuse the name or perform general Active Directory housekeeping.

To run the Remove-UMDialplan cmdlet, the account you use must be delegated the Exchange Organization Administrator role.
