Audio Video not working in IE, Chrome and Firefox

[raanam]

I tried to run Audio Video functionality from IE 11, Chrome 55.xx and Firefox. But it does not seem to work in any of the browsers. I have installed Skype for Business Web App Plug-in as well but it does not seem to make any difference.
On the other hand Audio Video works well on Windows 10 + Edge.
Is there anything additional that needs to be done in order to make it work on browsers except Edge. Please let me know.

Audio worked on IE11, Chrome 55.xxx. It need ssl for your website.
Current, Camera had request browser permission, but it not show,.

This document has more details on supported browsers: https://msdn.microsoft.com/en-us/skype/websdk/docs/gettingstarted#sectionSection1

Edge is supported via ORTC (pluginless) and IE11 and Safari are supported via the plug-in.

Anyone get any further with webRTC plugin-less functionality in Chrome/Firefox?
