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. For more information about Unified Messaging dial plans, see Understanding Unified Messaging Dial Plans.
The result pane enables you to view a subset of properties for a UM dial plan. This includes the UM servers, IP gateways, and mailbox policies that are associated with the UM dial plan.
- UM Dial Plan
This column in the result pane lets you view the display name for each dial plan that has been created. If your organization uses multiple dial plans, you should use meaningful names when naming them. The maximum length for a display name is 64 characters and it can contain spaces.
- # digits
This column in the result pane lets you view the number of digits found in the extension numbers for the dial plan. You configure the number of digits for the dial plan when you create it.
- Associated UM Servers
This column in the result pane lets you view the Unified Messaging servers that are associated with this dial plan. A single or multiple Unified Messaging servers can be associated with a UM dial plan.
- Associated UM IP Gateways
This column in the result pane lets you view the UM IP gateways that are associated with the dial plan. After you create a dial plan, you must create at least one UM IP gateway and UM hunt group. The UM IP gateway can be associated with a dial plan by using the New UM IP Gateway wizard.
