A UM dial plan has been created. For detailed steps, see Create a UM Dial Plan.

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. In the work pane, on the UM Dial Plans tab, select the UM dial plan you want to manage, and then click Properties in the action pane.
   
   
3. On the dial plan Properties page, click the Features tab.
   
   
4. Under Callers can contact, select one of the following options:
   
   
   1. Users within this dial plan   Use this option to allow callers who call in to a subscriber access number to locate and contact users who are within the dial plan associated with the UM auto attendant.
      
      
   2. Anyone in the default global address list   Use this option to allow callers who call in to a subscriber access number to locate and contact anyone who's listed in the global address list. This includes all users who are mailbox-enabled.
      
      
   3. Only this extension   Use this option to allow callers to connect to an extension number that you specify. You can only use numeric digits for the extension. The number of digits that you define in this field must match the number of digits in the extension numbers that are configured on the UM dial plan.
      
      
   4. Only this auto attendant   Use this option to allow callers who call in to a subscriber access number to connect to a specific auto attendant. You must create the auto attendant before you specify it here. This allows callers to be transferred to another auto attendant. The auto attendant you choose here can be a speech-enabled or non speech-enabled auto attendant.
      
      
   5. Anyone in address list   Use this option to allow callers who call in to a subscriber access number to locate and contact users who are in a defined custom address list. This includes all users who are mailbox-enabled.
      
      
5. Click OK to save your changes.
