Telephony.muted

The muted property of the Telephony interface indicates whether or not the microphone is muted for the purposes of telephony.

Syntax

// Is the phone muted?
var muted = myTelephony.muted;

// Mutes the phone
myTelephony.muted = true;

Value

 A Boolean — true indicates the microphone is muted; false indicates that it is not. You may read and write this value.

Examples

// Telephony object
var tel = navigator.mozTelephony;

// Receive a call
tel.onincoming = function (e) {
  var incomingCall = e.call;

  // Answer the call
  incomingCall.answer();
};

// Say we have a button that mutes/unmutes the phone
muteButton.onclick = function() {
  if(tel.muted) {
    tel.muted = false;
  } else {
    tel.muted = true;
  }
}
