Microsoft Internet Explorer does not natively support WebRTC technology. WebRTC (Web Real-Time Communication) is a technology that enables real-time voice and video communication directly within web pages without requiring additional plugins or software. Over its development history, Internet Explorer has not incorporated support for this modern web communication standard.
Conversely, Microsoft began supporting WebRTC in its later-released Edge browser. The first version of Edge, based on Microsoft's own EdgeHTML rendering engine, supported WebRTC starting with the release of Windows 10. More recent versions of Edge, particularly the Chromium-based Edge, continue to support and enhance WebRTC capabilities.
Therefore, to use WebRTC technology on Microsoft browsers, it is recommended to use the latest version of Microsoft Edge.
