[Users] OpenSER dimensioning. How many calls/sec can it set up?

[Bogdan-Andrei Iancu]

Hi,

simple SIP-Proxy  refer to a simple config file, like the one provided 
by default by openser.
Performance will decrease once your script complexity increases.

but notice that if you do not use any kind of media relay, the proxy is 
not affected by the number of parallel calls since it;s transaction 
stateful and not dialog stateful....so you can have hundred of thousands 
of call in parallel with 0 load on the proxy.

regards,
bogdan
