title: IVR integration using php
body: <p>Is it possible to integrate IVR with PHP ?
  is there any tutorial or links related to the same?</p>
  
  <p>I want, 
  When a user calls certain phone number and input their booking registration number and booking date, IVR should response the booking order, and status to the user by automatic voice.</p>
  
  <p>Is it possible to implement with PHP (CodeIgniter)?</p>
