Hello , I would like to share with you the email below that I exchanged with the representative of Mera Systems. I was about to evaluate their product when I stumbled with FS. He, of course, is trying to say that FS is not able to support more than 300 simultaneous calls and that I should buy their product. Anyway, the intention is only to ask for some comments from the guys who really know how FS behave in a production environment. Thank you Jair Santos Hi Jair, We have over 1000 high-end developers on staff in Russia, we write software for Nortel (Meridian PBXes), Siemens, Alcatel, Ericsson, etc. Why would we use Asterisk as a core for our systems? Some of our products can deliver Call Per Second rates up to 1000, I guess about 50 times more than Asterisk :))) Might be that someone telling this to you mixed us with PortaOne, a Ukrainian developer. They, indeed, use Asterisk and SER in their products, like most other companies selling "their" switching solutions. In any case, as a start-up the path you are taling is reasonable, but I really doubt you will stay on Freeswitch once you hit 300 calls in peak. Or - you will need to run lots of unbinded servers with separate IPs, each supporting some 300 calls.

The information from the FS home page. Performance * Tested under load for over 100 hours * 10,000,000+ calls * At rates exceeding 50 CPS Performance will vary depending on application. You will need to test for your particular situation. Retrieved from "http://wiki.freeswitch.org/wiki/Specsheet"
