Windows 10 users can now make Skype video and voice calls inside the Microsoft Edge web browser without the need to download a plugin program. This is due to the recent addition of the ORTC media engine that is now embedded inside Edge.
In a blog post, Microsoft stated that this new support can be accessed when using Skype for Web, Outlook.com, Office Online and OneDrive from the Edge browser:
Because the Skype and Microsoft Edge teams work so closely, it means you'll be able to take advantage of plugin free calling in certain calling scenarios from Microsoft's Edge browser first. All Skype one-to-one and group voice and video calls to and from Microsoft Edge browsers are plugin free. All Skype one-to-one calls from Microsoft Edge to the latest versions of Skype for Windows and Skype for Mac are plug in free.
The blog added that the Skype team is working to add similar support for Chrome and Firefox, when those browsers start using the H.264 video codec. Microsoft recently announced a roadmap for extending its support for real time communication in Edge.
