thanks again. If I understand correctly, you are saying that there is a 
switch that allows a user to adjust the volume of the "background" music 
only, but the incoming speech that is coming in to him from other users 
will not get adjusted? That's awesome, but I can't find anything like 
that in the docs.

Will your example

[bridge_user_menu]
*1=increase_listening_volume
1=increase_listening_volume
*2=decrease_listening_volume
2=decrease_listening_volume

not just decrease/increase the audio of *everything* that is coming in 
to the user, i.e. both music and speech? At least that it's how it's 
explained in the documentation, isn't it?

"Decreases the caller's listening volume. *Everything* they hear will 
sound quieter."

What I'm looking for is to adjust the incoming music only, not the 
incoming speech. How is ConfBridge able to separate between these two if 
they are going on at the same time?

Done that couple of times, but I still don't see that "feature".

I think there is still some sort of misunderstanding here. Maybe I'm not 
explaining it right...

Thanks!
