title: iOS: use VOiP notification instead of "normal" notif
body: <p>We just add VOiP capability to our app (messaging app), now we will use VOiP (<a href="https://developer.apple.com/library/prerelease/ios/documentation/NetworkingInternet/Reference/PushKit_Framework/index.html" rel="nofollow noreferrer">PushKit Framework</a>).</p>
  
  <p>Can anyone tell me if we can use only that notifications (VOIP notifications)? Meaning even for text message for example (not for a call)? I talk about Apple Appstore Guides, they can reject the app or block the notifications if they found that we use that notification to notify the user about other things then a VOIP call?</p>
