Abstract

PURPOSE:To avoid the noise of a bell sound due to an annoying phone, etc., by deciding whether there is a voice or not in a device and preventing a receiving person from being called when the voice is mute. CONSTITUTION:Means 2 and 3 to close a loop and, simultaneously, to decide the existence of voice from a transmitting side when a calling signal sent from an exchange is detected, and means 6 and 9 to compulsorily interrupt a call when the voice from the transmitting side is mute and to ring a bell at a receiving side when there is a voice, are provided. Thus, when a receiving is executed, an automatic response is executed, and whether there is a voice from the transmitting side or not is decided, and when there is no voice, a call is compulsorily interrupted, and only when there is a voice, the bell is rung. Therefore, the annoying phone, etc., can be driven back and the noise of the ringing of the bell due to the annoying phone can be avoided.
