Enable or Disable Outgoing Calls on a UM IP Gateway

  • Article

 

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

You can enable or disable outgoing calls for a Unified Messaging (UM) IP gateway in Microsoft Exchange Server 2010 Unified Messaging. 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 doesn't affect call transfers or incoming calls from an IP gateway.

Outdialing is the term 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

To allow outdialing for UM-enabled users, you must:

  • Verify that the UM IP gateway allows outgoing calls.

  • Create dialing rule groups by creating dialing rule entries on the UM dial plan associated with the UM IP gateway.

  • Add the correct dialing rule groups to the list of dialing restrictions on the Dialing Restrictions tab on the UM dial plan and on the UM mailbox policy.
