Abstract: A interactive value-added telecommunications system including automatic billing at a value-added rate controllable in real time is realized through in-place network carrier system utilities including multiparty switching which verify a calling party by a telephone number, and optionally a PIN number, and provides for calling party authorization of billing at a rate established by the called party. The system enables a method for conducting a business wherein a party calls for a service or product, is identified via one or two separate code sequences, requests a service or product from the called provider who establishes a rate for compliance. The caller authorizes and initiates the established charge to an account associated with one of said code sequences which preferably is a telephone number associated with a credit or debit account by completing a third-party call to a designated value-added number.
