ABSTRACT:
A telephone system and method of operation are disclosed which use a microprocessor control system (10), a speech generator (34) and speech memory (46) to interact with a calling party placing a long distance phone call. The telephone receives a billing account number from the calling party through a keypad (24). The telephone determines the validity of the billing account number and, if the billing account number is valid, a communication path is established through a telephone line interface (38). Valid billing account numbers are stored in the telephone for a predetermined period of time. The stored numbers are polled prior to the validation process to determine if an entered number has already been validated. In this manner, a calling party making multiple calls with the same billing account number need only wait for his account number to be verified once.
