What is WebRTC?

WebRTC (Web Real-Time Communication) is an open-source technology that enables real-time voice, video, and data communication directly in web browsers and mobile apps without requiring plugins or additional software.

WebRTC uses peer-to-peer connections with STUN/TURN servers for NAT traversal. It supports adaptive bitrate, echo cancellation, noise suppression, and encryption by default. Use cases include browser-based softphones, video calls, and screen sharing.

InboxCentral leverages WebRTC for browser-based calling, enabling agents to make and receive calls directly from the unified inbox without additional software.
