Abstract
The network control system, servicing a long distance carrier switching office, is provided with a caller's automatic number identification (ANI) when a calling party calls a called party. Using a database, a processor of the network control system determines call type characteristics of the telephone call based on the received ANI for wireless and land-line telephone calls. The network control system then returns either an index or routing information to the long distance carrier switching office. After the ANI is screened by the network control system, subsequent call processing takes place in the long distance carrier switching office.
