title: Use VoLTE protocols in an app
body: <p>VoLTE is a relatively newer technology. I understand that calls made using VoLTE use internet data (The same data that we use to browse the internet, watch YouTube videos etc.) It kind of fascinates me. I tried getting more info about how it works  and came to know that VoLTE is something like an "optimized" data network for Voice (Which makes it much better than VoIP). My question is:</p>
  
  <p>Q. 1) If it is "optimised" data network, then how come we make VoLTE calls using the same general purpose internet.
  Q. 2) Is the optimization done on the client side.
  If YES for Q. 2), what are those optimizations and how to use them in an android app. Is there any library for it? (For Ex. <a href="https://github.com/DoubangoTelecom/doubango" rel="nofollow">This</a>)</p>
  
  <p>Q. 3) Also, does VoLTE means an end to VoIP and hence an end for Skype, Facetime etc.? Can Skype or Facetime port their mobile apps to use VoLTE over VoIP?</p>
