Hi, I built a FARM OF ASTERISKs split into 3 geographically dispersed sites (for high aggregate bandwidth concerns). There were 60 machines in total. All of them Dual Xeon 3.0 with 2GB. [ This turned out to be way more CPU that I needed.] Each machine had 18~24 separate conference "rooms". All rooms were available on all 60 machines. All 60 machines had 18 ~24 voice feeds (one into each conference. At peak loads every machine also had a maximum of 220 participants listening - - mixed among the different conferences available. I was listening DTMF codes from any listener to allow switching from room-to-room. But no audio allowed from the listeners.
I designed very carefully to avoid any trans-coding from the point where the sound was first captured - - in the dirver's seat of a NASCAR race car. This was done for several years of live races broadcasts with amazing voice quality. At peak we had over 6,000 simultaneous callers listening. There. were no issues on Asterisk or SuperMicro machine performance. I had one major foul-up when 18,000 new call attempts came in within a 5 minute period and the regional telephone system of Southern California jammed up and dropped 10,000+ calls before the every reached the Asterisks. NOT AN URBAN LEGEND. This was deployed by a team of 3 guys using Asterisk 1.4.x in less than 30 days including purchase shipping of the SuperMicro 1-U machines, configuring the Asterisks, deploying to COLO sites, and cross connecting (via pre-existing SIP carrier gateways) with over 250 Nortel DMS switches in the mobile phone networks. ..mike..
