WebRTC Foundation

Trainer(s): Wolfgang Liegel, duration: 2 days (2x 8 hours)

WebRTC is a specification implemented in almost all modern web browsers. Using simple Javascript and HTML5 you can make your webpage a communication platform providing secure audio, video, data and desktop sharing. The biggest video conferencing tools make use of this open specification, which is integrated in many web browsers and libraries.
In this Workshop, we will teach you all you need that is required to create a basic WebRTC Client and Server for voice and video communication.

Detailed description
Day 1: our WebRTC Essentials training.
Day 2: On this day, we will use open source tools to implement a callcenter application, which will be able to connect to your local PBX or public switched telephone network (PSTN). You will learn how to use Javascript libraries and the open source project Asterisk as a VoIP Gateway for connecting WebRTC Clients to a local PBX or PSTN. You will learn how to setup a basic configuration and dialplan to handle calls from a customer on her/his web browser. Of course you will also learn about security considerations, when implementing your own service. At the end of this lesson, you will be able to call your mobile phone by using just a regular web browser.

On request, the trainer can also provide a deeper knowledge of technologies like (S)RTP, Codecs, STUN/TURN/ICE, NAT, TLS and end2end encryption provided by WebRTC.
