title: Can I register Web RTC app as Calling app
body: <blockquote>
  <p>I have web rtc implemented in a webview. Everything working fine as long as app in foreground.</p>
  </blockquote>
  <p>Now if the app is in <strong>background/dose</strong> mode. I want to show a <strong>ringing screen like what's app</strong>.
  I am having a push notification when some one calls.</p>
  <p>I know I can show notification alnog with calling sound and onClick of the notification . I can show my app Activity.</p>
  <p><em>Is there any call urls exist like</em> <a href="https://stackoverflow.com/questions/2430045/how-to-register-some-url-namespace-myapp-app-start-for-accessing-your-progr"><strong>this</strong></a></p>
  <p>and can it be <strong>handled without notification</strong></p>
  <p>Or can I register my app as calling app. So that whenever call happens I register <a href="https://developer.android.com/reference/android/telecom/ConnectionService" rel="nofollow noreferrer">ConnectionService</a></p>
  <p>and recieve <code>onCreateIncomingConnection</code></p>
