We have a machine with a quad core 'Intel(R) Xeon(R) CPU E5-1410 0 @
2.80GHz' running asterisk 11.2-cert with ingress and egress all sip.
Fastagi running as a daemon (written in perl) performing cdr updates
at call start, answer and call end together with a query when a call
comes in to get information on what to do with it. Local Mysql 5.5
database.<br>
With all this we easily handled 450 simultaneous calls with many of
them also performing call recording. I think we typically had 60%
idle on each processor so the box could be pushed a lot more.<br>

How did the system behave with 244 calls? I’ve been able to
make 1,024 concurrent faxes (which tend to use more
resources than audio calls) in the lab. The problem I had
was after the faxes were transmitted, things couldn’t keep
up and kept dumping core. Two things were going on, (1) the
CDR was written to MySQL and (2) a FastAGI script (I use the
AGISpeedy PERL package) to write a log entry also to MySQL.
I tried switching the CDR’s to sqlite and that seemed able
to keep up, except that its concurrency issues were a
problem. If MySQL is the problem, I could probably optimize
it better, but it doesn’t explain the Asterisk core dumps.
It might be related to the number of FastAGI scripts
running, I’m not sure at this point.<o:p></o:p></span></p>

<p class="MsoNormal" style="text-align:justify">The better
question is, maximum number of users (IP Phones) can your
hardware support. I have * deployments with 300-600 phones.
- works fine. though concurrent calls has never seen more
then 244. Also at this point I have to ask, for this to be
any concern to you, you must either A, Make tons of internal
calls. OR B have multiple T1's/lots of sip channels? <o:p></o:p></p>
