Hi Maxim, We found another bug that you maybe will be able to fix in 4.0.2, l'll try to explain here.
If 2 persons (or more) are in the same room and open their microphone, as one of the person leave the room, it's look like the AUDIO channel stay open. Even if the person is OUT of the room, we will still be able to hear his voice (AUDIO). This bug is reprodicible alo on the DEMO server (4.0.1). It's only their with IE. Please keep me inform if you have time to test it out ?
