This topic explains how to use the Exchange Management Console and the Exchange Management Shell to configure a subscriber access number on a Unified Messaging (UM) dial plan. A subscriber access number lets a UM-enabled user access their Microsoft Exchange Server 2007 mailbox by using Outlook Voice Access. When you configure a subscriber access number on a dial plan, UM-enabled users can call in to the subscriber access number, log on to their Exchange 2007 mailbox, and access their e-mail, voice mail, calendar, and personal contact information.
By default, when you create a UM dial plan, a subscriber access number is not configured. To configure a subscriber access number, you must first create the dial plan and then configure a subscriber access number on the dial plan's Subscriber Access tab. Although a subscriber access number is not required, you must configure at least a single subscriber access number to enable a UM-enabled user to use Outlook Voice Access to access to their Exchange 2007 mailbox. You can also configure multiple subscriber access numbers for a single dial plan. For more information about UM dial plans, see Understanding Unified Messaging Dial Plans.
For more information about the menu options that are available for Outlook Voice Access users, see the Quick Reference Guide for Outlook Voice Access, which is available from the Microsoft Download Center.
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 2007, see Permission Considerations.
Also, before you perform these procedures, confirm that a UM dial plan has been created.
In the console tree of the Exchange Management Console, expand the Organization Configuration node, and then click the Unified Messaging node.
On the UM Dial Plans tab, select the UM dial plan that you want to manage, and then click Properties in the action pane.
On the dial plan Properties page, click the Subscriber Access tab.
Under Associated Subscriber Access Numbers, enter the subscriber access number in the box that is labeled Enter the telephone number to associate, and then click the Add button.
Click OK to save your changes.
Run the following command:
Set-UMDialPlan -identity MyUMDialPlan -AccessTelephoneNumbers 4255551234
