PURPOSE:To inform a name of an outgoing station to a called extension in response to a private line incoming call by allowing the 2nd storage means for storing a name of the outgoing station to read the name of the outgoing station before the connection of the private line and the called extension when the called extension replies. CONSTITUTION:When a central controller 17 receives a dial pulse via an incoming register 20, an allocated position of an extension 11 is read from a number of the called extension 11 to start a ringing circuit of a line circuit 12 connected and to ring a bell of the extension 11. On the other hand, an identification code of the outgoing station fed to a memory corresponding to a private line trunk 14 is stored. When the extension 11 hooks off, the central controller 17 detects the state change in the line circuit 12 and when it is judged that the extension 11 replies, the identification code of the outgoing station is extracted from the memory corresponding to the private line trunk 14, the name of the outgoing station is read from a storage means 19 for storing the name of the outgoing station corresponding to the identification code, the line circuit 12 connected to the called extension 11 and a voice equipment 21 are connected by a switch 13 and the sending of the name of the outgoing station from the equipment 21 is commanded.
