Hi all,
i need to test how many calls can withstand an Asterisk server.
Do you know any good tools to strain the server?
At best, there are scripts that I can run on a Linux server.
I thank you for your tips
Sincerely
Dominique Haeber

SIPP is probably what you seek. http://sipp.sourceforge.net/
Hope this helps.

Another approach is to use another Asterisk system.
Recently, a customer wanted to confirm his platform would support 500
simultaneous calls.
I wrote a quick bash script to dump 500 call files (at a leisurely pace)
into another host that originated calls to the target host.

Thanks in advance,

Steve, would you be willing to share that "quick bash script"?

There's no magic in the script, but here it is, embarrassing myself:
cp sample-call-file /tmp/
chmod +x /tmp/sample-call-file
for I in $(seq 1 $1)
do
sudo -u asterisk\
cp /tmp/sample-call-file\
/var/spool/asterisk/outgoing/${RANDOM}
done
sleep 10
Here's what's wrong with this snippet:
1) I don't know why I chmod the 'template.' No idea whatsoever. Alcohol
may have been involved.
2) I hate single character variable names. I love alcohol.
3) cp is ill advised. For a testing script, it was easy. For a production
application, use mv.
In use, I would execute it specifying how many call files to create, like
50. Then, take a look at top, iftop, and vmstat. Lather, rinse, repeat to
get to your goal.

We started the 500 calls and used milliwatt app on the first and record
on the second host to check the quality. Alternatively just start 500+
calls and call yourself on top. So you can get a good idea how the
quality is.
Call-Files are explained on

Hi,
Â
Curious why didn’t you try AQuA to score the quality? Using voice files for tests has more representation to my opinion.

Thanks,

That's a fascinating concept!
Can you share any more about how you appraised the data and determined your results?
ie once you had the recordings on the second host what did you do do computationally score them? Do you look at the decoded (1khz?) waveform or do you appraise in another way?

Hi Pete,
we used different approaches.
Just to test the maximum channels a gateway can process the two Methods are enough, you can either listen to the Recordings or look at the waveform.
The easiest approach is to call a colleague and gradually increase the calls on the machine.
For systematic, continuous analysis Voipmonitor is a very useful tool.
We directed the traffic to a mirroring port on the Switch to which we connected a Server running Voipmon. (http://www.voipmonitor.org/)
Voipmon records the call and rates its quality. You can check the results either using the commercial Web Interface (test for free) or query the mysql DB.
Unfortunately Voipmon tends to crash on a regular basis (at least when we used it), but it's an awesome tool.
The underlying tool pcapsipdump is running a lot more stable, but you need to put a lot more work into it to get started.
hope i could help

The control file needs some training but I was successful to the
goal, thanks again.
