Hi guys,  
digging in the webrtc discussions I came across this post:  
[https://bugs.chromium.org/p/webrtc/issues/detail?id=9268](https://bugs.chromium.org/p/webrtc/issues/detail?id=9268)

I noticed that licode needs a few secs to “see” that there’s no more an high layer.

How does it work in licode?
