How to Create a Unified Messaging SIP URI Dial Plan

Microsoft Exchange Server 2007 will reach end of support on April 11, 2017. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

 

Applies to: Exchange Server 2007, Exchange Server 2007 SP1, Exchange Server 2007 SP2, Exchange Server 2007 SP3

This topic explains how to use the Exchange Management Console and the Exchange Management Shell to create a new Unified Messaging (UM) dial plan in Microsoft Exchange Server 2007 Unified Messaging. A UM dial plan has an organization-wide scope and contains all configuration information that is related to a telephony system. A UM dial plan establishes a link from the telephone extension number of an Exchange 2007 recipient in the Active Directory directory service to a UM-enabled mailbox.

Note

After the new UM dial plan is created, a Unified Messaging server must be associated with the UM dial plan.

Important

Each time that you create a UM dial plan, a UM mailbox policy is also created. The UM mailbox policy is named <DialPlanName> Default Policy.

New in Exchange 2007 Service Pack 1 (SP1)

When you create a dial plan by using the New Dial Plan wizard, you can configure the Uniform Resource Identifier (URI) type and the level of Voice over IP (VoIP) security to be used. For more information about the URI types for UM dial plans, see Understanding Unified Messaging Dial Plans.

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 2007, see Permission Considerations.

Procedure

Exchange 2007 SP1

To use the Exchange Management Console to create a new Unified Messaging SIP dial plan

  1. In the console tree, expand the Organization Configuration node, and then click the Unified Messaging node.

  2. In the action pane, click New UM Dial Plan.

  3. In the New UM Dial Plan Wizard, on the New UM Dial Plan page, in the Name field, type the name of the dial plan. The UM dial plan name that you type must be unique.

    Important

    Although the field for the name of the dial plan can accept 64 characters, the name of the dial plan cannot be longer than 49 characters. If you try to create a dial plan name that contains more than 49 characters, you will receive an error message. The message will say that the dial plan name could not be created because a default UM mailbox policy name could not be generated because the UM dial plan name is too long. This happens because, when you create a dial plan, a default UM mailbox policy is also created that has the name <DialPlanName> Default Policy. Therefore, the name of the UM mailbox policy is 15 characters longer than the name of the dial plan.

  4. On the New UM Dial Plan page, in the Number of digits in extension numbers section, type the number of digits in the extension numbers for the UM dial plan.

  5. On the New UM Dial Plan page, in the URI Type drop-down list, select SIP URI.

  6. On the New UM Dial Plan page, in the VoIP security drop-down list select one of the following options:

    • SIP secured

    • Unsecured (default)

    • Secured

  7. On the New UM Dial Plan page, click New.

  8. On the Completion page, click Finish.
