PURPOSE: To simplify the dialing to an opposite subscriber having a common local station number and toll number by providing a function redialing only the station number.

CONSTITUTION: A control section 2 transfers a dial number dialed by a subscriber to a station number recognition section 3 entirely, the station number recognition section 3 indexes only the station number, and the indexed station number is stored in a memory section 4. When the subscriber makes dialing, if the called party is the destination in the station number dialed previously, the station number stored in the memory section 4 is transferred to the control section 2 by depressing a key section 5 and the control section 2 dials only the transferred station number. Thus, when dialing is frequent to called parties with the same toll station number and local number but different subscriber number, the succeeding subscriber number has only to be dialed and number of dialing operation is reduced.
