发明名称 Single-line, plug-in telephone answering machine
摘要 An answering machine with one or more special features. These features include either means for providing multiple out-going messages, or multiple in-coming message locations, or both, with the message locations being selectable by the caller by means of preselected code sequences entered by the owner. When both portions of the present invention are present there are two sets of code sequences, one for out-going messages and another for in-coming messages. The number of digits in each code sequence can be the same or different, as can the actual codes since the detection of the proper code is time dependent on where in the cycle of the answering sequence the answering machine is at the time that the caller enters the code sequence.
