[Freeswitch-users] Conference talk detection

[Anthony Minessale]

We use a conference with energy detection on 12+ hours a day and I don't
recall losing any of the audio.
The instant you breach the level that same packet is sent, and you have to
have several consecutive packets below the level to stop.

My guess is you are talking to something lame like a Sonus who is resetting
its jitterbuffer when you start talking again.

try editing your profile and adding this param

<param name="conference-flags" value="waste-bandwidth"/>

This will make the conference send rtp to the other side of the call even
when you are not talking which typically soothes unruly RTP devices.
