You might be able to setup a single top node conference, then bridge
in lower node conferences. In this situation you could have 6 lower
node boxes each with 50 callers into it, and each of the 6 lower
node conferences called into the single top node conference(along
with your main audio producing stream(the professor, etc). This
would be a bit more complicated to control for muting, etc.<br>

I have an existing application that uses speex16(flash
voip) and I can get 50 callers in a single conference
before cpu gets to 70% on a c1.medium instance. I know
I can throw more hardware at the problem, but
interested in bridging the same conference number
between multiple freeswitch instances and presenting
single ESL notifications back to the existing
application so all users events are seen.<o:p></o:p></span></b></p>
