This topic explains how to use the Exchange Management Console and the Exchange Management Shell to enable or disable outgoing calls for a UM IP gateway in Microsoft Exchange Server 2007 Unified Messaging (UM). By default, when you create a UM IP gateway, it will allow UM-enabled users to place outgoing calls, or "dial out", of the UM-enabled user's dial plan. Outdialing is the term that is used to describe a situation in which a user in one UM dial plan initiates a call to another UM-enabled user in another dial plan or to an external telephone number. If you disable outgoing calls on a UM IP gateway, users who are associated with the dial plan will be unable to make outgoing calls through the IP gateway that is defined in the Address field on the properties for the UM IP gateway.
Outdialing enables UM-enabled users to initiate calls from inside an organization that has Exchange 2007 Unified Messaging. For outdialing to function correctly, certain settings must be configured. These settings include the following:
Dialing group rules Dialing group rules determine the types of calls that 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 PBX or IP PBX.
Dialing restrictions Dialing restrictions are the restrictions that are applied to prevent users from incurring unnecessary telephone charges for your organization or from dialing long distance calls.
To allow outdialing for UM-enabled users, you must:
Verify that the UM IP gateway will allow outgoing calls.
Create dialing rule groups by creating dialing rule entries on the UM dial plan that is associated with the UM IP gateway.
Create dialing restrictions on the UM mailbox policy that is associated with the same dial plan as the UM IP gateway.
When you select the Allow outgoing calls through this UM IP gateway check box on the properties for the UM IP gateway, you configure the UM IP gateway to accept and send outgoing calls to an IP gateway. If you clear the check box, you prevent the UM IP gateway from sending outgoing calls to an IP gateway. Although the Allow outgoing calls through this UM IP gateway setting controls whether the IP gateway is able to initiate outgoing calls for users, it does not affect call transfers or incoming calls from an IP gateway.
