You can configure dialing rule groups for a Unified Messaging (UM) dial plan in Microsoft Exchange Server 2010. Dialing rule groups specify settings for in-country/region and international calls that will be placed by UM-enabled users from inside your organization. After you create a dialing rule group, you must add a dialing group entry. Each dialing rule entry that's defined in the dialing rule group determines the types of calls, in-country/region or international, that users within a specific dialing rule group can make when they place outgoing calls. By default, UM-enabled users aren't allowed to dial external telephone numbers from inside the organization. However, they're allowed to dial UM-enabled users who are associated with the same dial plan.

After you create the UM dial plan with an in-country/region or international dialing rule group and configure the dialing rule entries, you must add the dialing rule group to the dialing restrictions on the UM mailbox policy associated with the UM dial plan. When you add the dialing rule group to the dialing restrictions on the UM mailbox policy, the settings you use will apply to all UM-enabled users associated with the UM mailbox policy. For more information about how to create dialing rule entries, see Create a Dialing Rule Entry on a UM Dial Plan.

Important:
If you've integrated Exchange Unified Messaging and Office Communications Server, you'll probably find it unnecessary to configure dialing rules or dialing rule groups in Exchange Unified Messaging. Office Communications Server is designed to perform call routing and number translation for users in your organization, and will also do this when the calls are made by Exchange Unified Messaging on behalf of users.

Prerequisites

A UM dial plan has been created. For detailed steps, see Create a UM Dial Plan.

Use the EMC to configure in-country/region dialing rule groups

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "UM dial plans" entry in the Unified Messaging Permissions topic.

  1. In the console tree, navigate to Organization Configuration > Unified Messaging.

  2. In the work pane, click the UM Dial Plans tab.

  3. Select the dial plan you want to modify, and then, in the action pane, click Properties.

  4. On the Dialing Rule Groups tab, under In-Country/Region Rule Groups, do one of the following:

    • Click Add to add a dialing rule entry. On the Dialing Rule Entry page, enter the number mask and the number to be dialed for the dialing rule entry. A number mask is represented by a series of Xs or asterisks and replaces the number of digits that follow the prefix for a telephone number, for example, 91425xxxxxxx, or 91425*. If a number that's dialed by a caller matches the prefix configured in the dialing rule entry, the PBX will dial the number that was specified in the Dialed number field.

    • Click Edit to change the in-country/region dialing rule entry settings.

    • Click Remove to delete the in-country/region dialing rule entry.

  5. Click OK to save your changes.

Use the EMC to configure international dialing rule groups

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "UM dial plans" entry in the Unified Messaging Permissions topic.

Use the Shell to configure in-country/region dialing rule groups

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "UM dial plans" entry in the Unified Messaging Permissions topic.

This example configures a UM dial plan named MyDialPlan with in-country or region dialing rules.

Copy Code 
$csv=import-csv "C:\MyInCountryGroups.csv"
Set-UMDialPlan -Identity MyDialPlan -ConfiguredInCountryGroups $csv
Set-UMDialPlan -Identity MyDialPlan -AllowedInCountryGroups "local, long distance"

Use the Shell to configure international dialing rule groups

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "UM dial plans" entry in the Unified Messaging Permissions topic.

This example configures a UM dial plan named MyDialPlan with international dialing rules.

Copy Code 
$csv=import-csv "C:\MyInternationalGroups.csv"
Set-UMDialPlan -Identity MyDialPlan -ConfiguredInternationalGroups $csv
Set-UMDialPlan -Identity MyDialPlan -AllowedInternationalGroups "local, long distance"
