Enable Dialing Restrictions on a UM Mailbox Policy

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

Topic Last Modified: 2012-07-23

You can use the EMC and the Shell to enable dialing restrictions on a Unified Messaging (UM) mailbox policy in Microsoft Exchange Server 2010. A dialing restriction is used to configure dialing rules that can be used to prohibit users associated with a UM mailbox policy from making certain types of telephone calls.

Dialing restrictions are used when you configure outdialing for UM-enabled users and can be used when you want to enable users to place calls to in-country/region or international telephone numbers. When you configure a setting on a UM mailbox policy, that setting will apply to all UM-enabled users associated with the UM mailbox policy.

Outdialing enables UM-enabled users to initiate calls from inside an organization that has Unified Messaging. For outdialing to work correctly, certain settings must be configured correctly. These settings include:

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 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 applied to prevent users from incurring unnecessary telephone charges or from dialing long distance calls.
