We have setup a new conference service and it works well, except for some complaints here and there about the voice quality;
I was then wondering what are the recommended values for comfort noise and energy level as per your experience for conferences?
My feeling is that comfort noise should be disabled but I am unsure about the energy level; is this a try and see parameter, or should it ideally simply be set to 0 or a small value for a conference call system?
