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

The onconnected event handler of the TelephonyCall interface is a reference to a function to be called to handle the Telephony API's connected event.

This event occurs when the call completes the connection process. The event handler is called with a CallEvent as its only parameter.


myCall.onconnected = function() { ... };


// Telephony object
var tel = navigator.mozTelephony;

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

  call.onconnected = function(e) {
    console.log('Your call to ' + + ' is connected.');
