发明名称 Telephone apparatus for recording a predetermined message in place of a CNG tone
摘要 An telephone answering apparatus connected to a facsimile apparatus. A controller transmits a response message stored in a memory to the line, and starts recording an incoming message inputted from the line into the memory. In a case where a tone detector detects a tone signal, the controller releases the line and records a switching message stored in the memory instead of the incoming message. This prevents wasting incoming message storing capacity due to recording a tone signal and erroneous operation of the facsimile apparatus caused by reproducing a recorded tone signal.
