PURPOSE:To make surely a call to an object user without requiring useless connection exchange job by providing a telephone set inputting and registering an incoming number specific to the user other than the incoming number specific to a telephone set and an exchange registering the incoming number intrinsic to the user inputted from the said telephone set. CONSTITUTION:The user uses a ten-key to depress the desired incoming number for itself, e.g., a code being continuity of a desired number in a prescribed digit number. When the incoming number intrinsic to the user is inputted and registered, the number is stored in a memory of a telephone set, inputted to a line circuit 26 as a digital signal, and the registered incoming number is transferred from the line circuit 26 to a central processing unit 23 of a control system 30. The central processing unit 23 registers the incoming number intrinsic to the registered user by changing a part of the table stored while the incoming number intrinsic to a telephone set 24 or 25 corresponds to the personal incoming number of the user. |
