Abstract

PURPOSE:To attain calling of one and same extension again after the end of talking by one touch operation by providing a means storing number information of a caller side extension and reading the number information of the caller extension to be stored through the operation of the called side extension after the end of talking for each called extension between extensions. CONSTITUTION:An extension 1 is hooked off to call an extension telephone set 2, and as soon as the extension 2 is hooked off for the reply, a central controller 4 sends number information of the extension 1 being a caller side to a storage means 5 of the caller extension and writes it in a memory corresponding to the extension 2. Simultaneously, the central controller 4 brings the extensions 1, 2 in the talking state through a connection path 6 of a switch network 3. After the end of extension call, when the extension is hooked off, the connection path 6 is cut off via the switch network 3. The extension 2 is hooked off and the one-touch key is operated, the operation is detected by the central controller 4 to read extension number information of the extension 1 from the storage means 5 thereby applying call control to the extension 1.
