1. A communication terminal for informing a user of a received call from a remote caller by an alert sound, comprising:

  • an alert sound generator for generating the alert sound when the call is received from the remote caller;

    control means for controlling said alert sound generator; and

    means for specifying a predetermined operation by the user, wherein when said alert sound generator is generating the alert sound and said means for specifying said predetermined operation is operated by the user, said control means controls said alert sound generator to change a volume of the generated alert sound only for the received call, without affecting the volume of the alert sound for future received calls, while leaving a call ringing state, as perceived by the remote caller, of the call to the terminal from the remote caller unchanged.
