title: Is there any way to catch phone call answer event?
body: <p>I try to catch phone call answer event, is it even possible using react-native? 
  <br/>At this moment I'm using <a href="https://github.com/priteshrnandgaonkar/react-native-call-detection" rel="nofollow noreferrer">https://github.com/priteshrnandgaonkar/react-native-call-detection</a>. At the start of call I catch Offhook event which is fine, but I really need to catch phone answer event.<br/>
  All help and tips are appreciated. Thanks!</p>
  
  <pre><code>    startListenerTapped() {
  this.callDetector = new CallDetectorManager((event)=&gt; {
  // For iOS event will be either "Connected",
  // "Disconnected","Dialing" and "Incoming"
  
  // For Android event will be either "Offhook",
  // "Disconnected", "Incoming" or "Missed"
  
  
  if (event === 'Disconnected') {
  // Do something call got disconnected
  } 
  else if (event === 'Connected') {
  // Do something call got connected
  // This clause will only be executed for iOS
  } 
  else if (event === 'Incoming') {
  // Do something call got incoming
  }
  else if (event === 'Dialing') {
  // Do something call got dialing
  // This clause will only be executed for iOS
  } 
  else if (event === 'Offhook') {
  //Device call state: Off-hook. 
  // At least one call exists that is dialing,
  // active, or on hold, 
  // and no calls are ringing or waiting.
  // This clause will only be executed for Android
  }
  else if (event === 'Missed') {
      // Do something call got missed
      // This clause will only be executed for Android
  }
  },
