A Unified Messaging dial plan is an Active Directory object that is a logical representation of a Private Branch eXchange (PBX) or telephony dial plan. A UM dial plan is a logical object that establishes a link between the users within a UM dial plan and a telephony network. A dial plan is created by using an organization-wide scope and contains all the configuration information that is related to your telephony network.
