The onconnected property of the Telephony interface specifies an event listener to receive connected events. These events occur when the phone is connected to the call group.
Syntax
myTelephonyCallGroup.onconnected = function() { ... };
These events are of type CallEvent.
Examples
// Telephony object
var tel = navigator.mozTelephony;
// Make two calls; assume they are both answered
var call1, call2;
tel.dial(number1).then(call => call1 = call);
tel.dial(number2).then(call => call2 = call);
// Add both calls to the conference call
// Two entries will appear in conference.calls (call1, call2)
// but nothing in tel.calls
var conference = tel.conferenceGroup;
conference.add(call1, call2);
conference.onconnected = function() {
  // When the phone connects to the conference call, do something
};
