This topic explains how to use the Exchange Management Console and the Exchange Management Shell to configure dial codes on a Microsoft Exchange Server 2007 Unified Messaging (UM) dial plan. You can configure dial codes, national number prefixes, and in-country/region and international number formats that are used by a Unified Messaging server to dial incoming and outgoing calls for users who are enabled for Unified Messaging. In most cases, you will configure a dial plan with the dial codes and national number prefix that are currently configured on your telephony network.

Dial codes, national number prefixes, and formats are used by a Unified Messaging server to determine the correct number to dial for an outgoing call that is placed by a UM-enabled user. On the Dial Codes tab, you can also configure the Unified Messaging servers that are associated with the dial plan to match the incoming call number format for both in-country/region and international numbers. When you configure the in-country/region and international number formats, you can restrict incoming calls for users who are associated with a dial plan. For more information about dial codes, national number prefixes, and in-country/region and international number formats, see Understanding Dial Codes, Number Prefixes, and Number Formats.

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.

Also, before you perform these procedures, confirm that a UM dial plan has been created.
