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. William King Senior Engineer Quentus Technologies, INC 1037 NE 65th St Suite 273 Seattle, WA 98115 Main: (877) 211-9337 Office: (206) 388-4772 Cell: (253) 686-5518 william.king@quentustech.com On 08/24/2012 04:15 AM, Stephen Dame wrote:

*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?*
