title: iOS 7, private API to disconnect calls CTCallDisconnect does not work
body: <p>I have been using a private API (for personal use not on the App Store) to block incoming calls using the steps outlined in this Stackoverflow post <a href="https://stackoverflow.com/questions/7326338/how-can-i-use-private-apis-to-block-incoming-calls-in-an-ios-application">How can I use private APIs to block incoming calls in an iOS application?</a></p>
  
  <p>I recently upgraded to iOS 7 and discovered that it does not work anymore.  I still receive the "kCTCallIdentificationChangeNotification" notification when an incoming call is received, but when I call the CTCallDisconnect function, it does nothing.</p>
  
  <p>When I do the "nm" command on the CoreTelephony library, it still lists the CTCallDisconnect function so it looks like it's still present in iOS 7.</p>
  
  <p>Has anyone had any luck in rejecting incoming calls in iOS 7?</p>
  
  <p>Thanks!</p>
