TelephonyCallGroup.onheld

This API is available on Firefox OS for internal applications only.

The onheld property of the Telephony interface specifies an event listener to receive held events. These events occur when the call group is successfully put on hold.

Syntax

myTelephonyCallGroup.onheld = 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.onheld = function() {
  // Do something when the conference call
  // is successfully held
};
