[asterisk-biz] Asterisk Performance Results

[Zoa]

It is not because they cannot test more than 5000 simultaneous calls in 
their lab, that by using openser they can't scale more.
openser is known to handle more than people can throw at it (especially 
if you dont care about the packets per second and run it stateless, it 
will scale to anything you ask it to), and by using it to load balance 
asterisk, it can in theory handle an unlimited amount of calls.
(if you dont care about the call setups per second).
