We want to set up a production system handling at least 1000 users per server, but ideally on the order of 100,000 users on one server. This would temporarily replace a local, or even regional, school system (pro-bono work, but they'd pay server costs; this will obviously cost a lot less than they're going to need to pay the more established company).

Most of these people will need to use a Hebrew conference interface, so we also need to know if freeswitch/src/mod/say/mod_say_he/mod_say_he.c is production-ready.

In the worst-case-scenario (which is obviously crazy), where everyone is talking at once, and these people are in anywhere from 10-30 person conferences (classes), what are the needed server specs?

In a more realistic scenario, where a maximum of 2 people are talking at once per conference:

• 20,000 users speaking, 2 per each of the 10,000 conferences
• ~6700 users speaking, 2 per each of the ~3300 conferences

Or, 3 people at once:

• 30,000 users speaking, 3 per each of the 10,000 conferences
• ~10,000 users speaking, 3 per each of the ~33,333 conferences

What are the variables here? My friend runs Bestfone, and —while he handles tens of thousands of calls a month— he doesn't handle that many simultaneous calls, so we're trying to figure out exactly what level of power is needed here.

Please help! We're trying to literally help thousands of school kids (over 124,527, as of last official numbers) if that motivates you.

Thanks!
