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 thorugh a keypad (24). The telephone determines the validity of the billing account number by attempting to place a telephone call using the billing account number to a controlled telephone number. If the attempt is successful the billing account number is valid and a communication path is established through a telephone line interface (38). The microprocessor controlled system (10) generates a billing record for the call which is stored in a call record memory (11). The billing record can later be retrieved to facilitate billing the call.
