A telephone answering system is provided which includes an automatic ring delay circuit which sets the system so that the first call received after the system has been turned on requires four rings, for example, to activate the system, and all subsequent calls require but two rings, for example. The telephone answering system also includes an oscillator circuit which is momentarily energized at the end of an announcement interval so as to generate a beep signal to the calling party to notify the calling party that the system is now in condition to record his message.
