PURPOSE:To efficiently transmit a message, by reading out the dial number of the telephone system of a transfer opposite, sendins the message through a prescribed time of nonaudio state after detecting a reception voice, and operating an automatic answering telephone set when no reception voice is detected in a prescribed time. CONSTITUTION:By operating a keyboard 8, the dial numbers of the telephone systems, for example, 2, 3, and 4 of the transfer opposites are stored in a memory 15, and simultaneously, the message desired to be transferred is recorded at a recording and reproducing device 9. Next, by depressing a transfer start button, a network device 10 is connected to a telephone line, and also, the dial signal of the device 2 is read out from the memory 15, and a dial device 11 performs the dial call of the device 2. In this way, the call tone of the device 2 is sent to a device 1. At this time, the device 1 is set at a state to detect the presence/absence of a voice signal from the line, then, the call tone is detected. Simultaneously, an intermittent signal tone is sent from an intermittent tone oscillator 12 to the line via the device 1. At this time, by raising a handset by a transfer opponent, and generating the nonaudio state for the prescribed time, the message is outputted. When a receiver is absent, the automatic answering telephone set 5 is operated.
