The ability to see the reason for the incoming call is required in certain call center applications. The reason for the call can be determined from two items: Dialed Number Identification Service (DNIS) information and call-attached data. DNIS is the number dialed by the calling party, for example, the order hotline telephone number or the services telephone number.

You can customize DNIS to translate the phone number to a description and to display that description along with the phone number.

The Call State subscreen has a field showing DNIS and the accompanying description field.
