Speakerphones are available for providing total voice terminal operation without the use of the handset. Turning on the speakerphone is equivalent to lifting the voice terminal handset when placing or answering a call. Turning off the speakerphone is equivalent to hanging up the handset. The microphone switch temporarily cuts off transmission to the distant party during a call.
