This topic explains how to use the Exchange Management Console and the Exchange Management Shell to enable dialing restrictions on a UM dial plan in Microsoft Exchange Server 2007 Unified Messaging (UM). To perform these procedures, you must have Exchange 2007 Service Pack 1 installed. Dialing restrictions are used to configure dialing rules that can be used to prohibit users who call in to a subscriber access number that is configured on a UM dial plan from making certain types of telephone calls. Dialing restrictions are also used when you want to allow users to place calls to in-country/region or international telephone numbers. When you configure dialing restrictions and configure outdialing on a UM dial plan, the dialing restrictions that you configure will apply to all UM-enabled or Outlook Voice Access users who are associated with the UM dial plan and to anonymous callers when they call in to a subscriber access number that is configured on the UM dial plan.

Outdialing occurs when a Unified Messaging server places an outgoing call for a user after they have called in to a subscriber access number on a UM dial plan or to a UM auto attendant. For outdialing to function, the following settings must be configured correctly:

Dialing group rules Dialing group rules determine the types of calls that users within a dialing group can make. Dialing group rules include the following:

Dialing rule entries Dialing rule entries define the number that is dialed by the user and the actual number that will be dialed by the Private Branch eXchange (PBX) or IP PBX.
Dialing restrictions Dialing restrictions determine the restrictions that will be applied to prevent users from incurring unauthorized telephone charges for your organization or from dialing long distance calls.

To enable outdialing for 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 dial plan that is associated with the same UM IP gateway.

Before You Begin

To perform the following procedures, the account you use must be delegated the Exchange Organization Administrators 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 the following:

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

Procedure

To use the Exchange Management Console to enable dialing restrictions on a UM dial plan for in-country/region rule groups

In the console tree of the Exchange Management Console, expand the Organization Configuration node.
Click Unified Messaging.
In the work pane, click the UM Dial Plans tab.
Select the UM dial plan that you want to modify, and then, in the action pane, click Properties.

On the Select Allowed In-Country/Region Groups page, select the dialing rule group that was configured on the UM dial plan, and then click OK.
Click OK to save your changes.

To use the Exchange Management Console to enable dialing restrictions on a UM dial plan for international rule groups
