Claims

[Scope of utility model registration request]

In a telephone device equipped with a caller selection function that emits a ringing signal when the number corresponding to the DTMF signal sent by the caller after incoming call operation matches the PIN number, when the telephone device is in the caller selection operation state. A first response message sending circuit which enters an operating state when an incoming call is performed due to the arrival of a calling signal and sends a response message to the calling party, and a number and a password corresponding to the DTMF signal sent by the calling party. a number matching circuit that performs matching and outputs a driving signal when the numbers match; a calling signal generating circuit that enters an operating state and generates a calling signal when the driving signal is output from the number matching circuit; When an incoming call operation is performed in response to the arrival of a paging signal in the caller selection operating state, the circuit enters an operating state for a predetermined period of time, and when another incoming call operation is performed within the predetermined time period, the calling signal generation circuit is brought into an operating state. a paging operation control circuit that outputs a driving signal to prompt the caller; and a second response message sending circuit that becomes operational when the driving signal is output from the number verification circuit or the paging operation control circuit and sends a response message to the caller. A telephone device for making a call, characterized in that, during a calling operation by the calling operation control circuit, the first response message sending circuit is made inactive and the second answering message sending circuit is made to be in the operating state. user selection circuit.
