It's quite suitable if the desire is simply to route based on that
criteria.
However, it falls apart once you start looking for to do some of the
other things commercial SBCs out there do per se.
99% of our business comes from Kamailio-related consulting. We've done
plenty of those projects. We've had folks come to us looking for us to
build SBCs, complete with media hairpinning, to front Metaswitches and
so on. It's not a good idea. Never again. Nowadays, when they're
looking for something like that, I send them looking toward SEMS (SIP
Express Media Server), or the SBC appliance that Frafos has
commercialised on top of it:

Can the vm handle transcoding or is it primarily sip signaling?

That's signalling and proxying media for most of the calls; no transcoding
beyond u-law <-> A-law.

Hi Grant -
We use FreeSWITCH running on CentOS, virtualised with OpenVZ. The largest
instances run up to
4,000 sessions (=2,000 concurrent calls) and have peaked at over 40
calls/sec; they use less than
half of an i7-3770 CPU at this level.

200 concurrent calls would be a good start with 20 calls a second.
If there is a platform that can be virtualized on my current equipment, that
would be the preferred method. We have a high available cloud that currently
runs many Centos virtual PBX instances.

How many concurrent calls?
How many calls per second?

We would need to be able to route calls to and from different IP addresses
based on source and destination.
