Chapter 7. WebRTC and Mod_Verto

WebRTC is all the rage these days. And with a cause! Maybe you end up buying this book just to know how you can release your existing services to hundreds of millions of browsers out there, or maybe you want to start coding the next killer app from scratch.

Anyway, you're on the right path; read on. You'll find both the needed theory and real world implementation examples.

In this chapter we will cover:

  • What WebRTC is and how it works
  • Encryption and NAT traversing (STUN, TURN, etc)
  • Signaling and media
  • Interconnection with PSTN and SIP networks
  • FreeSWITCH as a WebRTC server, gateway, and application server
  • SIP signaling clients with JavaScript (SIP.js)
  • Verto signaling clients with JavaScript (mod_verto, verto.js)
