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

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

This event occurs when the call has finished being disconnected from the network. The event handler is called with a CallEvent as its only parameter.


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


// Telephony object
var tel = navigator.mozTelephony;

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

  call.ondisconnected = function(e) {
    console.log('Your call to ' + + ' has finished.');
