A subscriber access number lets a user who is enabled for Unified Messaging (UM) access a mailbox in Microsoft Exchange Server 2010 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 2010 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 isn't configured. To configure a subscriber access number, you first need to create the dial plan and then configure a subscriber access number on the dial plan's Subscriber Access tab. Although a subscriber access number isn't required, you need to configure at least one subscriber access number to enable a UM-enabled user to use Outlook Voice Access to access to their Exchange 2010 mailbox. You can also configure multiple subscriber access numbers for a single dial plan.

For more information about the menu options available for Outlook Voice Access users, see the Quick Reference Guide for Outlook Voice Access, which is available from the Microsoft Download Center.
