The telephone includes a touch sensor which may be attached on a handset. When the telephone receives a call meant therefor, the telephone alerts the user to the call by outputting a ringing tone through a speaker. In response to the call, the telephone also transmits a signaling tone to a base station which may be connected to the telephone over a radio channel and to a public switching telephone network. If the user touches on the touch sensor in response to the ringing tone, the telephone stops the signaling tone and thus informs the base station that the user has responded to the call.
