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.

This topic explains how to use the Exchange Management Console and the Exchange Management Shell to configure an extension number for a Unified Messaging (UM) dial plan. You can configure this setting to transfer calls to a UM auto attendant, if one is configured, a human operator, external telephone numbers, or extension numbers. When you configure an operator extension number on a UM dial plan, a caller can connect to the dial plan operator by doing one of the following:

  • Pressing the zero (0) key.

  • Saying "Reception".

  • Saying "Operator".


If the caller exceeds the maximum number of touchtone or voice input retries, they are also transferred to the operator extension number, if you have defined an operator extension number and enabled business hours operator transfers.

Before You Begin

To perform this procedure, the account you use must be delegated the following 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 that a UM dial plan has been created.
