Your handset is equipped with a handsfree talking feature. When you activate
the handsfree talking function, you can hear the person you are talking to loud

handset in your hands or in front of your mouth.
While making the phone call, you can switch off the microphone in your hand-
set. The earpiece remains On in that process. The person you are connected
