A related piece of information conveyed to the Inward WATS subscriber is the Dialed Number Identification Service (DNIS), the number that the caller dialed when accessing the service. With the information, the service provider can have several toll-free numbers directed to the same call center and provide unique service based on the number dialed. DNIS can also be used to identify other call routing information. For example, the WATS service can be configured to send a specific DNIS number that is assigned to callers from geographic regions based on city, area code, state, or country.
ANI has two components, information digits, which identify the class of service, and the calling party telephone number.
