[Freeswitch-users] How to calculate server requirements for Freeswitch.

[Cal Leeming [Simplicity Media Ltd]]

This is a perfectly valid question, but like many technical implementations
it is purely dependent on what it is you're trying to do and how you're
trying to do it.

Real life benchmark information is something that is lacking but there's
nothing much that can be done about it. Although benchmarks would give some
indications on ratios (for example, showing the CPS/jitter difference
between answering a call with a media file, and answering it with IVR), it
would involve having to test a lot of combinations. However it could also
be argued that writing such benchmarks would be a complete waste of time,
there are literally so many combinations you could use that the benchmarks
would be a little importance.

I think what speaks louder than benchmarks, is the number of successful
production deployments that are utilizing FreeSWITCH, and the testimonials
from people like Ken who are pushing millions of calls a month. There are
several large providers using this in production, and several write ups of
real life numbers already in production.

Perhaps we need to put together a better wiki page for newcomers who ask
this question, as it does seem to be asked quite a lot.
