PURPOSE:To attain the incoming display distinguished from other incoming call from a specific incoming call by providing a memory registering a telephone number to a terminal equipment and collating the sender number information with a telephone number registered in the memory at the incoming call. CONSTITUTION:When a registration setting code is sent from a dial 2, a CPU 5 applies write preparation of a registration telephone number into the memory 6 and writes a telephone number sent next in a prescribed space of the memory 6. The CPU 5 stops the registration control by a registration operation end signal sent finally. When the incoming call comes and a all signal and ID information are sent to a telephone line L, the call signal and the ID information are inputted to an incoming detection circuit 4 via a hook switch 9. The CPU 5 collates the ID information received from the line L with the telephone number registered in the memory 6 and when the ID information is coincident with one of the registered telephone numbers in the memory 6, an incoming display device 7 is rung by the 1st display tone and bya the 2nd display tone when not coincident. Thus, a specific incoming call is displayed while being distinguished from other incoming calls.
