Abstract
An apparatus, method and system are illustrated which provide for calling party number determination and manipulation, utilizing digit analysis. One of the switch embodiments includes a network interface, a memory, and a processor. The network interface receives an incoming message having a received calling party number and transmits an outgoing message. The memory stores, as a database module, a plurality of digit trees for digit analysis and a plurality of available manipulations. The processor includes instructions to perform digit analysis of the received calling party number to determine a pattern match and to determine a selected manipulation of the plurality of available manipulations, and to perform the selected manipulation on the received calling party number to form a modified calling party number. The processor includes further instructions, when a pattern match has been determined, to direct the network interface to transmit the modified calling party number in the outgoing message, and when a pattern match has not been determined, to direct the network interface to transmit the received calling party number in the outgoing message. The database module may be modified …
