TelephonyCall.onholding

The event handler is called with a CallEvent as its only parameter.

Examples

// Telephony object
var tel = navigator.mozTelephony;

// Place a call
tel.dial("123456789").then(function(call) {
  call.number;

  call.onholding = function(e) {
    console.log('Your call to ' + e.call.id + ' is being put on hold.');
  }
});
