ABSTRACT:
When a telephone apparatus makes a particular and emergency call using a telephone communication line and another telephone apparatus is already performing communications using the telephone communication line, then the control apparatus controls refers to a particular/emergency number table stored in a storage device and disconnects the communications that are currently being performed to transmit signals for the particular and emergency call. The control apparatus disconnects the communications and also reconnects the disconnected communications using an Internet communication line by referring to a line use status table stored in the storage device. At the time of the disconnection, an announcement that the communications are to be disconnected is also made beforehand to the telephone apparatus the communications over which are to be disconnected.
