[Freeswitch-users] Strange media behavior on WebRTC

Wed Jun 4 07:30:40 MSD 2014

OK, thanks.  It's still happening with the latest master, so I have to
assume that this is something to do with the AWS VMs.  It would not be the
first time strange things happen there.

I was trying to work around the problem and noticed that if instead of
playing the beep using playback app before placing the user into the
conference, I make the beep the enter-sound of the conference, the problem
does not happen.

However, I need to only play this sound for users joining the conference
from one dialplan but not from another.  I cannot find a way to do it.  I
looked at
<action application="set"
data="conference_enter_sound=silence_stream://10"/>
but it changes the enter sound for the conference for everyone, so anyone
entering after the user who set this up will hear the same sound.

Is there a way to assign conference params per user (like member flags)?
