Automatic generation of billing records at a telephone paystation

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 establishes a communication path 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 include information such as an account number to be billed, destination determining information, the duration of the call, the time of the call, and rate information. The billing record can later be retrieved from a remote location through standard telephone lines to facilitate billing the call. The local generation of billing records facilitates billing for direct calls, collect calls, third party charge calls and calls associated with accounts which are key-padded into the telephone paystation by the customer.
