In this case, the call-forward information (dial designated address information) is given to the telephone 1b of the calling side. Then the telephone of the calling side can select whether or not a connection is given to the telephone at the call-forward address with a specific operation of telephone. A central processor 6 contains a deciding means and a circuit connection control means to perform the above-mentioned processes.
