Enable Dialing Restrictions on a UM Dial Plan

 

Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

Topic Last Modified: 2012-07-23

You can enable dialing restrictions on a Unified Messaging (UM) dial plan in Microsoft Exchange Server 2010. Dialing restrictions are used to configure dialing rules that can be used to prohibit users who call in to a subscriber access number configured on a UM dial plan from making certain types of telephone calls. Dialing restrictions are also used when you want to allow users to place calls to in-country/region or international telephone numbers.

When you configure dialing restrictions and outdialing on a UM dial plan, the dialing restrictions that you configure will apply to all UM-enabled or Outlook Voice Access users associated with the UM dial plan and to anonymous callers when they call in to a subscriber access number configured on the UM dial plan.

For outdialing to work, the following settings must be configured correctly:

  • Dialing group rules   Dialing group rules determine the types of calls users within a dialing group can make. Dialing group rules include:
  • Dialing rule entries   Dialing rule entries define the number that is dialed by the user and the actual number that will be dialed by the Private Branch eXchange (PBX) or IP PBX.
  • Dialing restrictions   Dialing restrictions determine the restrictions that will be applied to prevent users from incurring unauthorized telephone charges or from dialing long distance calls.
