[asterisk-users] RTP Mixer

[Kapil Dhawan]

Perfect Josh...but if i am running an application which has a capability 
of showing number or participants depending upon CC value, that doesn't 
work. Secondly, Asterisk can show on CLI about current "talking" users 
where it is maintaining talking status but not sending it down the line 
to be used by other apps.

Anyways, i will go with your statement and leave it on core developers 
to comment.
