26 ABSTRACT A new method of charging enhanced service provider (ESP) fees on phone bills of telephone numbers originating seven digit 555 number calls within The Public Switched Telephone Network (PSTN). The Local Exchange Carrier routes the call to the PSTN which translates a dialed 7-digit 555 number into a ten-digit phantom routing number and then passes the call to the carrier assigned the ten-digit routing plan. Translation is performed as a look-up in a database, i.e., the Service Management System (SMS). The SMS is used for 800-number translation and was not heretofore available to ESPs. This novel use of PSTN facilities enables the system to provide caller dialed number and billing information on a real-time basis (during call processing). It signals the billing and caller dialed number information in the voice channel (In-Band) during setup of calls to connecting carriers. The ESPs receive the circuit "off-hook" signal (seizure), and two fields of Multi-Frequency Tones, then process the information to collect and validate billing information needed to deny the call or to accept it. If the ESP accepts the call, the caller dialed information is processed to bill or credit the subscriber for the service the caller selected. Using a phantom routing number bridging circuit between the Local Exchange Carriers and the toll carriers in a manner similar to 800 call processing allows the billing information to remain intact through- out the call hand-off from the carriers to the ESP.
