A communication apparatus for performing auto-redial processing for repetitively calling a distant station using a prestored call number until a connection can be attained, includes a response state detection unit for detecting a response state of the distant station or an exchanger through a line after a calling operation is started, and a control unit for judging according to a detection state of the response state detection unit whether or not the call number is correct, and for, when it is judged that the call number is false, interrupting the auto-redial processing.
