You can enable dialing authorizations on a Unified Messaging (UM) mailbox policy. You can use dialing authorizations on a mailbox policy to prohibit authenticated Outlook Voice Access users that are linked to the UM mailbox policy 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 mailbox policy, that setting applies to all UM-enabled users linked with the UM mailbox policy.

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