title: Receiving PushKit VoIP notifications iOS
body: <p>I'm integrating <code>PushKit</code> into my <code>iOS</code> app and have the client side code ready. I'm registering using <code>PKPushRegistry</code> and receiving the <code>PKPushCredential</code> with a token in my delegate. I'm registering this token to my server which is communicating with <code>APNS</code>.</p>
  
  <p>I can't find good documentation on what to send from my server to <code>APNS</code> to send a <code>VoIP</code> push notification to the client. Do I just send a normal remote notification request with content-available:1 to push by just replacing my Remote Notifications <code>.pem</code> with my <code>VoIP .pem</code>?</p>
