title: Awake application without using VoIP when user killed iOS application
body: <p>I am trying to develop whatsApp like calling feature in an application of mine.
  For audio call, I am using VoIP to initialize the CallKit and it's working perfectly.</p>
  
  <p>But I am not able to get Video call work just like whatsApp.</p>
  
  <p>If I assume that whatsApp is delivering is VoIP and then showing local notification. But as per iOS 13 documentation, you have to report incoming call to CallKit if you are using VoIP.</p>
  
  <p>And If I think of sending silent notification, it won't work if user killed the application manually.</p>
  
  <p>I have thought of many solutions but none behaves like whatsApp does. </p>
  
  <p>Can anyone help me with this? Any suggestion will be appreciated.</p>
