You can configure dial codes for a Unified Messaging (UM) dial plan in Microsoft Exchange Server 2010. You can configure dial codes, national number prefixes, and in-country/region and international number formats used by a Unified Messaging server to dial incoming and outgoing calls for users who are enabled for Unified Messaging. In most cases, you'll configure a dial plan with the dial codes and national number prefix 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's placed by a UM-enabled user. On the Dial Codes tab, you can also configure the Unified Messaging servers 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 associated with a dial plan.
