This topic explains how to use the Exchange Management Console and the Exchange Management Shell to enable dialing restrictions on a UM mailbox policy in Microsoft Exchange Server 2007 Unified Messaging (UM). A dialing restriction is used to configure dialing rules that can be used to prohibit users who are associated with a UM mailbox policy from making certain types of telephone calls. Dialing restrictions are used when you are configuring outdialing for UM-enabled users and can be used when you want to let users place calls to in-country/region or international telephone numbers. When you configure a setting on a UM mailbox policy, that setting will apply to all UM-enabled users who are associated with the UM mailbox policy.

Outdialing enables UM-enabled users to initiate calls from within an organization that has Exchange 2007 Unified Messaging. For outdialing to function correctly, certain settings must be configured correctly. These settings include the following:

Dialing group rules Dialing group rules determine the types of calls that users within a dial group can make.
Dialing rule entries Dialing rule entries define the number that is dialed by the UM-enabled user and the actual number that will be dialed by the PBX or IP PBX.
Dialing restrictions Dialing restrictions determine the restrictions that will be applied to prevent users from incurring unnecessary telephone charges for your organization or from dialing long distance calls.

To enable outdialing for UM-enabled users, you must:

Verify that the UM IP gateway will allow outgoing calls.
Create dialing rule groups by creating dialing rule entries on the UM dial plan that is associated with the UM IP gateway.
Create dialing restrictions on the UM mailbox policy that is associated with the same dial plan as the UM IP gateway.

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 the following:

A UM dial plan has been created.
A UM dialing rule group has been created.
A UM mailbox policy has been created.
