Abstract

When a communication apparatus determines that a LAN terminal designated by a transmitting facsimile machine has not logged on to the LAN, the communication apparatus sends a transfer result error back to the facsimile machine and sends the facsimile machine an inquiry as to what measures should be taken subsequently. Depending upon the response to the inquiry, either notification of the incoming call from the facsimile machine is transferred to a proxy user who has logged on to the LAN or it is determined, at fixed time intervals, whether the designated terminal or proxy user has logged on. If log-on can be confirmed, notification of the incoming call is transferred to or printed out. If log-on cannot be confirmed, the received data are erased. Refusal of an incoming call can thus be avoided even if the designated communication terminal on the LAN has not logged on.
