I
know a few commercial companies have scaled freeswitch
to handle 250-500 callers in a single conference across
boxes with direct audio cable connections in data
center.
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.
This
is a distance learning app, and not business audio
conference, so some latency is tolerable. I would
locate the multiple freeswitch servers in same zone and
possibly use the new high I/O EBS instances running in
SSD.
Any
thoughts on this?
