When CPU of a communication apparatus judges that a telephone line is not closed-and-connected and also judges that a transmission original is set, CPU performs processing of setting a transmission concentration. If it judges that no transmission original is set, the volume of a ringing sound is set. Further, when CPU judges that the telephone line is connected and closed and also judges that a telephone receiver is not on hook, it performs processing of setting a receiver volume. If it judges that the telephone receiver is on hook, it sets the volume of voices of a communication partner which are output from a speaker.
