Use the Dialing Restrictions tab on the Unified Messaging (UM) auto attendant properties to configure dialing rules for callers that call in to a UM auto attendant. An auto attendant is the collection of voice prompts that callers hear instead of a human operator when they call in to an organization that has Exchange 2007 Unified Messaging. You can use these settings to control the extension numbers that can be reached from an auto attendant or control the telephone numbers that can be dialed by callers that have dialed into the auto attendant.

attendant to place or transfer calls to an extension number that is

dial plan as the auto attendant. By default, this setting is
enabled.
- When you disable this setting, users who call in to an auto
attendant will be able to place or transfer calls to any non
UM-enabled users or other extension numbers that are not associated
with a UM-enabled user but will be unable to transfer calls to
UM-enabled users who are associated with the same dial plan as the
auto attendant. This is because the Allow calls to
extensions setting is enabled by default.
