You can enable dialing authorizations on a Unified Messaging (UM) dial plan. Dialing authorizations on a dial plan are used to prohibit unauthenticated Outlook Voice Access users from making in-country/region or international telephone calls, or outdialing. Outdialing happens when Unified Messaging places an outgoing call for a user after they've called in to an Outlook Voice Access phone number that is configured on a UM dial plan. When you configure a setting on a UM dial plan, that setting applies to all unauthenticated users that call in to an Outlook Voice Access number.

For additional management tasks related to outdialing, see Allowing Users to Make Calls Procedures.
