WebRTC basics

Estimated reading time: 1 min

WebRTC stands for “Web Real-time communication”. According to webrtc.org, WebRTC is a free, open project that provides browsers and mobile applications with real-time communication (RTC) capabilities via simple APIs.

In simple terms, it is a technology for real-time communication between two web browsers, communication can be via chat, audio or video communication, it doesn’t require any plug-in or any codec.

You just need to understand and learn the webRTC JavaScript APIs and you are ready to build browser-based communication apps.

What it is and How does it work?

WebRTC is a salient feature of the HTML5 specification, which is managed by the IETF and W3C. It can be enabled in the browser using JavaScript. Communication happens directly between the browsers without any involvement of webserver. A webserver is only required initially for handshaking and signaling between two devices.

Once the two devices are ready, the two browsers can directly communicate and webserver does not play any role. Currently, it is supported by Chrome, Mozilla, and Opera.

3 main APIs of WebRTC are-

  1. GetUserMedia – Get access to the camera, microphone, and screen of the device
  2. PeerConnection – This does everything, encodes and decodes media, sends it over the network
  3. DataChannel – Send data directly between the browsers

Usage in Contact Center Industry – A complete browser-based multichannel contact center can be build using WebRTC, agents can directly make and receive a call on the browser. It doesn’t require any plugin or additional software or hardware.

In many countries, mixing of PSNN and VoIP calls is not permitted you cannot start full-fledged webRTC based contact center. But still, a contact center can be set up with limited webRTC functionality.
