All phones come with a speaker and a microphone. The speaker is how you hear the person talking from the other end and the microphone is what you talk into so the person on the other end can hear you. However, if you are on a call and you do not want to the other person to hear what you have to say you can mute the call. Most phones, home and cell alike, have a simple mute button. However, if your phone does not have a mute button there may be a way to mute it using buttons or the display. Tips Writer Bio
