CONSTITUTION:A calling controller CONT writes non-connection information to a memory corresponding to an incoming subscriber allocation position by using the non-connection information 3 and writes a calling subscriber number 6 at non-connection corresponding to the incoming subscriber to a call information table 5. When the incoming subscriber B not connected hooks off, a central controller CC identifies whether or not the disconnected information exists, and when the information exists, talkie connection is attained, and informs the subscriber B the connection to the calling subscriber A next when the future subscriber is busy so as to connect the subscriber B to the subscriber A automatically. |
