This topic explains how to use the Exchange Management Console and the Exchange Management Shell to modify the existing properties of an Exchange Server 2007 Unified Messaging (UM) dial plan. When you modify the properties for the UM dial plan, you can choose to configure subscriber access settings, dial codes, IP gateways associated to the UM dial plan, and enable other call and fax answering properties for the UM dial plan.

To perform this procedure, 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.

Also, before you perform these procedures, confirm that a UM dial plan has been created.

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

  2. In the console tree, click Unified Messaging.

  3. In the work pane, on the UM Dial Plans tab, select the UM dial plan that you want to modify.

  4. In the action pane, click Properties.

  5. In the dial plan Properties window, select the configuration settings that you want to change, and then click OK to accept your changes.

  • Run the following command:

    Set-UMDialPlan -Identity MyDialPlan -AutomaticSpeechRecognitionEnabled:$true -AccessTelephoneNumbers 4255551000 -FaxEnabled:$true -WelcomeGreetingFilename welcome.wav -WelcomeGreetingEnabled:$true -InfoAnnouncementFilename info.wav -InfoAnnouncementEnabled:$true -LogonFailuresBeforeDisconnect 5 -OperatorExtension 512345 -AllowDialPlanSubscribers:$true -AllowExtensions:$true -Extension 51111 -UMAutoAttendant 51000 -InputFailuresBeforeDisconnect 5 -MaxCallDuration 15 -MaxRecordingDuration 5 -RecordingIdleTimeout 10 -Servers MyUMServerID -UMAutoAttendants MyAutoAttendant
