You can create a dialing rule entry for a dialing rule group on a Unified Messaging (UM) dial plan in Microsoft Exchange Server 2010. After you create an in-country/region or international dialing rule group on a UM dial plan, you must create a dialing rule entry for the dialing rule group.

A dialing rule entry defines the telephone numbers and number masks for in-country/region and international calls that can be made by UM-enabled users associated with a UM mailbox policy. Each dialing rule determines the types of calls users within a dialing rule group can make. However, you must correctly configure the dialing rule entry with a valid number mask and a dial number. After you create a dialing rule group and define the appropriate dialing rule entries on the Dialing Group Rules tab, you must add the appropriate dialing rule groups from the UM dial plan to a UM mailbox policy on the Dialing Restrictions tab.

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 a dialing rule entry

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. On the UM Dial Plans tab, select the UM dial plan you want to manage.

  3. In the action pane, click Properties.

  4. On the dial plan Properties page, under the Dialing Rule Groups tab, under In-Country/Region Rule Groups or International Rule Groups, click the Add button.

  5. On the Dialing Rule Entry page for the In-Country/Region Rule Groups or International Rule Groups, enter the following information:

    • Name   Use this list to select the name of an existing dialing rule group or, if you want to create a dialing rule group, type the name of the dialing rule group. This box can contain only text characters. The display name for the dialing rule entry can contain up to 32 characters.

    • Number mask   Use this box to define the number mask for the dialing rule. A number mask defines the telephone number format that a Unified Messaging server will use to determine what outgoing telephone number it will dial for a user. An example of a valid number mask is 91425xxxxxxx. This box can contain only numbers and the letter "x."

    • Dialed number   Use this box to define the dialed number for the dialing rule. The dialed number is used to determine the actual dial string that's sent to the IP gateway. This number can be different from the number that's obtained by Unified Messaging for the outgoing call. However, your Private Branch eXchange (PBX) can also be configured to omit the area code for local calls and can be configured for private voice numbering plans. Any wildcard (x) characters included in the dial string replace the digits from the original number that were matched by the number mask on the dialing rule. An example of a valid dialed number is 9xxxxxxx. This box can contain only numbers and the letter "x."

    • Comment   Use this box to enter a comment or description for the dialing rule that you are adding or modifying. By default, this box is blank.

  6. Click OK to save your changes.

Use the Shell to configure a dialing rule entry

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 dialing rule entry for an in-country/region rule group.

Copy Code 
Set-UMDialPlan -Identity MyUMDialPlan -ConfiguredInCountryOrRegionGroups <name, allowednumberstring, dialnumberstring, comment>

This example configures a dialing rule entry for an international rule group.

Copy Code 
Set-UMDialPlan -Identity MyUMDialPlan -ConfiguredInternationalGroups <name, allowednumberstring, dialnumberstring, comment>

For more information about syntax and parameters, see Set-UMDialplan.
