Running in IE with webrtc-everywhere

[alexrozrio]

I have downloaded https://github.com/oney/react-native-webrtc-server example. And run the server in node and checked the video calling between 2 machines it was working fine, but only in chrome and firefox.
I wanted to work it in IE and safari also. Hence i used https://github.com/DoubangoTelecom/webrtc-everywhere.

I have Download and install the plugin for Windows and Included adapter.js script in my code.
And replaced document.getElementById("eltId").src = mediaStream; to attachMediaStream(document.getElementById("eltId"), mediaStream);
But still it is not working in IE.
What am i missing?
Am i doing it correctly?

While debugging i can see, in Chrome, it is passing RTCSessionDescription in createOffer method and it has been passed to other machine and displaying the video.
[ In Console it prints RTCSessionDescription {type:offer sdp:<some_value>}
But it IE it is passing ISessionDescription and the object value is empty in console. (Strangely i can see the object value while debug the code in IE)
[In console it prints [object] { } ]

I am very much confused. I am relatively new to scripting hence i might have done very naive mistake too. Please correct me and help me.
I you want i can provide the code samples as well

Regards,
Alex.
