PURPOSE:To improve the operability by storing a caller number sent from the side of a network at an incoming call automatically, reading it at the moment of depression of a return dial switch and sending a signal by dialing to allow the caller side to redial in one touch. CONSTITUTION:When a caller number is sent from the network side from the incoming call, a processing section 7 writes the number in a designated address of a RAM 9. Then whether talking or untalking is judged and when in taking, a talking enable flag is set in a caller number memory and the address of the caller number memory is incremented by '1'. In case of untalking, a talking disable flag is set and the caller number memory address is incremented by 1. Then the caller number is stored in the RAM 9, and confirmed. Further, when a return dial switch 12 is depressed, the caller number represented by the caller number memory address is transferred in a display memory, outputted to a display device 11 and the caller number is dialed to the network side.
