Dialing Restrictions and Permissions

You can restrict outside calling from an extension that has access to an outside line.

Used to specify telephone numbers that extensions associated with the list can dial regardless of other dialing restrictions.

•Allowed List Assignments
Used to assign which allowed number lists an extension can use.

•Disallowed Phone Number Lists
