most likely you have a jitterbuffer on your phone that is recharging when you start talking. are you on the latest GIT where we have the waste bandwidth flag on permanently for all callers? To avoid problems like this conferences now always send rtp to people even when they are not getting any useful input.

Anthony,
The problem is not that audio is clipped because its "too silent", so adjusting the value seems to be the wrong handle for this problem.
It seems that the time needed to make the decision (regardless of the energy threshold value) is the core of the issue, i.e. the level may bei 100, 200 or 300, it takes some XX ms to detect talking and all audio that happens before the detection gets lost. Right?
Greetings, Roland

The setting is an arbitrary number of the energy score required to count as talking.
check your environments, its very specific to the surroundings. We run it at 200 in the main FS conf and its rarely an issue.

Setting it to 10 or so doesn't help, it seems that just the threshold of detection is changed (ok, that's what is expected), not the time until the decision is made.
The audio clipping is a timing issue. Does there exist something like a "minimum time" that this algorithm needs to detect talking after silence? What happens to the audio that was sent by that member during this time, does.the algorithm discard that?
