发明名称 Automatic generation of billing records.
摘要 <p>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 later be retrieved from a remote location through standard telephone lines to facilitate billing the call.</p>
