There was a problem. Note that although it is normally possible to call another extension from the telephone that received the call and use the called extension to talk to an outside line, it is possible that the called person may not be able to answer the call.

Another problem is that it requires the help of a third party. Furthermore, selective reception of telephones and faxes can be handled using the conventional technology described above, but the conventional technology relies only on operations on the sending side, and depends on the intention of the receiving side. The problem is that it cannot be transmitted.

The present invention solves the above-mentioned conventional problems, and provides a replacement adapter that can send a message to the person answering the incoming call, and then select whether to forward the call or send it to answering machine. The purpose is to provide
