Syntax

var secondCallerId = myCall.secondId;

Value

A TelephonyCallId object.

Examples

// Telephony object
var tel = navigator.mozTelephony;
// Receive a call
tel.onincoming = function (e) {
  var incomingCall = e.call;
  // Get the first and second caller ids of the incoming call
  console.log(incomingCall.id + ', ' + incomingCall.secondId);
  // Answer the call
  incomingCall.answer();
};
