Abstract
Upon reception of data via a PSTN (Public Switched Telephone Network), if a reception-result notification request is received from a transmitting apparatus, the state associated with the reception result as to whether or not the user of a terminal on the LAN has confirmed the data, is discriminated after completion of data reception and the disconnection of a line. Then, the discriminated information is notified by calling the transmitting apparatus. When the receiving apparatus is set to refuse notification by originating a call by itself, the information is notified in response to a call originated by the transmitting apparatus.
