[asterisk-users] Asterisk V/s FreeSwitch

[Danny Nicholas]

If the MOH thing is really true, a more "realistic" test would be to run
playback(demo-instruct).  Since I know that I will eventually cross this
bridge in real life/real time, I devised this test on my Asterisk 10.0 box

Dialplan (in default context)
exten => 3366,1,answer()
exten => 3366,n,playback(demo-instruct,noanswer)
exten => 3366,n,playback(demo-instruct,noanswer)
exten => 3366,n,playback(vm-goodbye,noanswer)
exten => 3366,n,hangup()

SIPP command
./sipp  -l 399 -d 99000 -m 399 -s 3366 -p 5061 -sn uac 127.0.0.1 -trace_err

I was able to do 260 concurrent calls with no issues.  The 2 playbacks for
demo-instruct were to cover 99 seconds since the file is only 67 seconds
long.  For the 300/1000 call scenario, you would need to duplicate the line
accordingly.  The limiting factor for me was my rtp.conf.  I set up a range
of 10001-10520 which stopped at 260 since each "call" allocates 4 rtp slots
(2 in use and 2 for transfer, etc).

this load tests are mostly about sip signal handling and not so much about
rtp streaming but this moh class which i use had 100 files and random set to
yes, so its atleast not soo bad.

This 330 concurrent calls was only the highest value which i had on a normal
production system and its really hard to build a test setup which presents a
system with 4000 sip peer doing some calls.

but the sound quality was still good even with 10000 calls in my tests.
