telephone can be connected to the TEL. SET socket on the your fax (note
that this socket is not available in some countries), or to the wall socket.
You can use an extension phone connected to the fax or a wall socket to
make and receive calls like any normal telephone. For details on
receiving faxes from the extension phone, see Chapter 4.
