II-digits provide information on the originating line for a call. You can use the information for some of following purposes:
Detect fraudulent orders for catalog sales, travel reservations, money transfers, and traveler’s checks.
Assign priority or special treatment to calls that are placed from pay phones, cellular phones, and motel phones. For example, an automobile emergency road service can prioritize calls placed from pay phones.
Detect calls placed from pay phones when the caller intentionally tries to prevent being tracked by collection agencies or dispatching services.
Convey the type of originating line on the agent display by routing different type calls to different VDNs.
