How to Enable or Disable Calls from Users Who Are Not UM-Enabled

 

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

This topic explains how to use the Exchange Management Console and the Exchange Management Shell to enable or disable calls from users who are not enabled for Unified Messaging (UM) to Microsoft Exchange Server 2007 recipients who are UM-enabled. By default, Unified Messaging allows incoming calls from unauthenticated callers through an auto attendant to be transferred to UM-enabled users. With this option enabled, users from outside an organization can transfer calls to UM-enabled users.

If this setting has been disabled for a UM-enabled user, the user's mailbox can still be located by using a directory search. However, if an external caller tries to transfer to the user, the system will say, "I'm sorry, I am unable to transfer the call to this user." The caller will be then transferred to the operator, if an operator has been configured on the auto attendant. If no operator has been configured on the auto attendant, the call will be transferred to a dial plan operator, if one has been configured. If no operator extension has been configured on the speech-enabled auto attendant, the DTMF fallback auto attendant, or the dial plan, the system will respond by saying, "Sorry. Neither the operator or the touchtone service are available."

For more information about how to manage UM auto attendants, see Managing Unified Messaging Auto Attendants.

For more information about how to manage UM dial plans, see Managing Unified Messaging Dial Plans.

To perform these procedures, the account you use must be delegated the Exchange Recipient 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:

  • The Exchange recipient has an Exchange 2007 mailbox.

  • The Exchange 2007 recipient is enabled for Unified Messaging.

  • A UM dial plan has been created.

  • A UM mailbox policy has been created.

  • The extension number that is assigned to the UM user is valid according to the UM dial plan that is defined.

  1. In the console tree of the Exchange Management Console, expand the Recipient Configuration node.

  2. In the result pane, select the user's mailbox that you want to view.

  3. In the action pane, click Properties.

  4. On the Mailbox Features tab, click Unified Messaging, and then click Properties.

  5. On the Unified Messaging Properties page, do one of the following:

    • To enable calls from users who are not UM-enabled, select the check box next to Allow UM calls from non-users.

    • To disable calls from users who are not UM-enabled, clear the check box next to Allow UM calls from non-users.

  6. Click OK to accept your changes.

  • Run the following command:

    Set UMMailbox -Identity tony@contoso.com -AllowUMCallsFromNonUsers <None | SearchEnabled>
