This topic explains how to use the Exchange Management Console and the Exchange Management Shell to create a new UM dial plan in Microsoft Exchange Server 2007 Unified Messaging. A UM dial plan is created with an organization-wide scope and contains all configuration information that is related to a telephony system. A UM dial plan establishes a link from the telephone extension number of an Exchange 2007 recipient in Active Directory to a UM-enabled mailbox.

Note:
After the new UM dial plan is created, a Unified Messaging server must be associated with the UM dial plan.

Important:
Each time that you create a UM dial plan, a UM mailbox policy is also created. The UM mailbox policy is named <DialPlanName> Default Policy.

New in Service Pack 1 (SP1)

When you create a dial plan by using the New Dial Plan wizard, you can configure the URI type and the level of VoIP security to be used.

Before You Begin

To perform the following procedures, the account you use must be delegated the Exchange Organization Administrator role.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange Server 2007, see Permission Considerations.

Procedure

Exchange 2007 SP1

To use the Exchange Management Console to create a new Unified Messaging dial plan

In the console tree, expand the Organization Configuration node, and then click the Unified Messaging node.
In the action pane, click New UM Dial Plan.

In the New UM Dial Plan wizard, on the New UM Dial Plan page, in the Name field, type the name of the dial plan. The UM dial plan name that you type must be unique.

Important:
Although the field for the name of the dial plan can accept 64 characters, the name of the dial plan cannot be longer than 49 characters. If you try to create a dial plan name that contains more than 49 characters, you will receive an error message. The message will say that the dial plan name could not be created because a default UM mailbox policy name could not be generated because the UM dial plan name is too long. This happens because when you create a dial plan, a default UM mailbox policy is also created that has the name <DialPlanName> Default Policy. Therefore, the name of the UM mailbox policy is 15 characters longer than the name of the dial plan. The name parameter for both the UM dial plan and UM mailbox policy can be 64 characters long. However, if the name of the dial plan is longer than 49 characters, the name of the default UM mailbox policy will be longer than 64 characters, and this is not allowed by the system.
