Further each of the terminals includes a halfway-saving & saving unit for saving a halfway response being created in a halfway-response recording file and for saving a completed response in a response recording file; a saved-halfway-response-reading unit for reading out the halfway response from the halfway-response recording file; a saved-halfway-response-display unit for displaying a halfway response stored in the halfway-response recording file read out by the saved-halfway-response-reading unit on the display unit; and a status-notifying unit for reporting status of being able or unable to receive an incoming call to the incoming-call control apparatus.
