A portable telephone is designed to control generation of musical tones and/or incoming call sound in response to classes of telephone numbers by which incoming calls are to be received. That is, the portable telephone stops generating musical tones while generating incoming call sound in response to telephone numbers of the first class; or it gradually decreases musical tones in tone volume in response to telephone numbers of the second class. In response to telephone numbers of the third class, the portable telephone continues generating musical tones without interruption while automatically disconnecting the line without generating incoming call sound.
