Enable Dialing Restrictions on a UM Auto Attendant

  • Article

 

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

You can enable dialing restrictions on a Unified Messaging (UM) auto attendant in Microsoft Exchange Server 2010. Dialing restrictions are used to enable dialing rules that can be used to prohibit users who call into a UM auto attendant from making certain types of telephone calls that are known as outdialing. Outdialing is the process that happens when a Unified Messaging server places an outgoing call for users after they've called into a subscriber access number on a UM dial plan or into a UM auto attendant.

When you enable dialing restrictions, the following settings must be configured correctly:

  • Dialing group rules   Dialing group rules determine the types of calls users within a dial group can make.

  • Dialing rule entries   Dialing rule entries define the number that is dialed by the UM-enabled 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 unnecessary telephone charges or from dialing long distance calls.
