The CPU 320 operates the voice message output unit 310 and outputs the guide message data to the voice signal processing unit 380. Next, the CPU 320 becomes a ready state for judging whether a DTMF(Dual Tone Multi Frequency) is received from the caller's telephone set.
• DTMF Dual Tone Multi Frequency
• the voice signal processing unit 380 processes the signal into a certain format so that a guide message data from the CPU 320 is transmitted via the telephone line, and the processed signal is transmitted to the caller's telephone set 500 via the connected telephone line and the switch 400. Therefore, the caller can hear a message "This is a post office box, and if you wish a switching control, press “1 ", and if you wish to input a recorded number, press "2", and if you wish a vice recording, press "3".

• the CPU 320 stores the recorded number into the memory 323 together with the called time and operates the voice message output unit 310, so that the subscriber hears a message "The number is inputted. Thank you”. Thereafter, the CPU 320 waits until the caller disconnects the call for about 10 seconds, and then the call is automatically disconnected. If the subscriber pushes the button "2", the CPU 320 operates the voice message output unit 310 so that the subscriber correctly inputs the number to be connected, for thereby informing the subscriber of the guide message.

In the case of the recorded message, the CPU 320 applies the address to the voice message output unit 310 and transmits the voice, which is recorded at a portion corresponding to the address, to the line connection unit 382. If the subscriber does not push the button, and a certain time(about 3 seconds) is elapsed, the CPU 320 automatically outputs the last message. In addition, after the last message is outputted, a guide message that "Press "1 " for hearing the message once more" is outputted to the subscriber.
• the CPU 320 In the case of checking the message based on the direct call by the subscriber, if the call ring is continued for a certain time, and the auto answering mode is set, the CPU 320 outputs a guide message. At this time, the subscriber pushes the button "4" irrespective of the guide message.
