title: Can we handle incoming call using VOIP push for twilio client?
body: <p>I have develop VOIP call functionality using TWilio Client iOS SDK.
  I get success to App to App call between two user. 
  I have three case for App to App call.</p>
  
  <p>Case 1 : User 1 and User 2. User 1 have a active app and User 2 have also active app. In this case I have successful establish call between them.</p>
  
  <p>Case 2 : User 1 and User 2. User 1 have a active app and User 2 have Inactive app(Background app mean minimize app). I have an implement local notification in this case and i get local notification.</p>
  
  <p>Case 3 : User 1 and User 2. User a have a active app and User 2 have a suspended app (App is kill). For this case i have implement voip push notification. User 2 get voip push notification. When user 2 click on push notification nothing happen. Call is not establish. </p>
  
  <p>I have manage twilio client token and also ask user to accept , reject and ignore call.</p>
  
  <p>I have message from twilio that use below link :
  <a href="https://www.twilio.com/help/faq/twilio-client/twilio-client-ios-sdk-background-best-practices" rel="nofollow noreferrer">https://www.twilio.com/help/faq/twilio-client/twilio-client-ios-sdk-background-best-practices</a></p>
  
  <p>I follow all step as mention in doc. But call is not establish after app is suspended (App is kill). How twilio client is listen current user when app is kill. How can we establish call ? many many question are in my mind.</p>
  
  <p>I post question previously in stack <a href="https://stackoverflow.com/questions/37802913/can-we-do-voip-push-notification-using-twilio-ios-sdk">Can we do VOIP push notification using Twilio iOS SDK?</a></p>

  <p>Please please help me as soon as possible.</p>
