[Asterisk-Users] Asterisk vs. Traditional PBX

Thu Feb 9 16:46:22 MST 2006

P-3 Xeon 550 w/ 23 B-channels concurrent - 150 SIP clients:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
 9712 asterisk  15   0 81556  11m 4392 S 18.9  0.4  11:19.06 asterisk

CPU is overrated.

Sorry to disagree, but unless you are transcoding or have a significant AGI
IVR or something, that server should be just fine. While I prefer a bigger
server for most installs, it is not because it is needed, more of a, money
well spent kind of thing. 

If you are transcoding and have an IVR, the picture is diferent.

The box I have been using is the Dell 1850 with SCSI RAID. May be overkill
for most applications, but it was under $2,000 so it made sense to me.

Hi Dovid,

Thank you for the book. I'm already reading it.

I have a dell 650 server, 1Gig of memory, 1 CPU ( 3.07Ghz).  What
hardware would you recommend for the 200 users w/ about 20 concurrent
calls ?

As always I thank you so much for your help.

I think your problem is the Dell 650. What are the
specs on it ? If you want a system that can support 
200 users you will need to do a lot better than that.
Also you will be dealing with T1's/E1's and not POTS
lines. I think a good place to start (if you havent
already) is the book that has come out a while back. I 
have it on my server at http://www.h6315.com/ast_book/

Regards,
Dovid
(I posted my server and not from the publisher becuase
I do not know thier URL and I have email access only 
now.)
