TelephonyCall.ongroupchange

The ongroupchange event handler of the TelephonyCall interface is a reference to a function to call when the call's TelephonyCallGroup (and therefore TelephonyCall.group property) changes.

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

Syntax

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

Examples

// Telephony object
var tel = navigator.mozTelephony;

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

  call.ongroupchange = function(e) {
    console.log('Your call's group has changed.');
  }
});
