PURPOSE: To inform how many number of times incoming calls exist to a user at a remote location in voice by allowing a voice synthesis circuit to inform the number of times of incoming calls to a caller in voice uttering number.

CONSTITUTION: This device increments a register at each incoming of voice within 4sec after the start of running of reception tape and stores the number of incoming calls to the register. On the other hand, a remote control signal from a caller is detected by a remote control signal detection circuit 7 and a test terminal T0 of a CPU. This remote control signal turns off a solenoid SD-1 or SD-2 to stop the tape under running. Then the value of data buses DB 0∼3 is brought into L or H level depending on the value of the register storing the number of times of incoming calls by means of a program to utter a corresponding numeral from the voice synthesis circuit 9, the numeral is amplified by an amplifier circcuit 5 and transmitted to telephone lines L1, L2.
