	Hello Matt,
Is that the Wildcard TE410P you are using.  Digium said that it had some
problems with Redhat 9.0 is that correct?

	- Digium quad T1 card
	- 3 T1's (2 x B8ZS ESF Long Distance and 1 x robbed-bit SF local)
	- Redhat 9.0

Hello,

Our max for a single machine is 40 concurrent SIP -> Zap conversations for
about a 12 hour period and over 5000 total phone calls per day. We didn't
see crashes going over that, but we wanted to be safe and now have 2
identical machines handling upto about 30 concurrent SIP -> Zap calls(3000
phone calls per day), and a third old machine for office use that never gets
over 10 concurrent calls. Here's the specs for these systems:

- 120 installed hardphones:
	- 80 x grandstream 102 hardphones
	- 20 x Sipura analog adapters(2 phones each)
- 2 x Asterisk servers
	- 2.6 GHz Pentium4 800MHz bus w/ HyperThreading enabled
	- Asus p4c800 800MHz mobo
	- 2GB DDR400 RAM (This is actually overkill you need 1GB max if you
reboot weekly)
	- 4 x 36GB SCSI drives in RAID 10 w/megaraid card
	- 3com 905CX ethernet card
	- Digium quad T1 card
	- 3 T1's (2 x B8ZS ESF Long Distance and 1 x robbed-bit SF local)
	- Redhat 9.0
	- Asterisk with many modules turned off and no MOH

With these servers you can see the load average jump from 0.00 to 6.25 in a
matter of a minute and then back down again, all while never dropping a call
or crashing.

We also recently diagnosed our lock-freeze to the touchy manager
interface(if you are logged into the manager interface and you loose
connection, the manager outgoing buffer seems to overflow and freeze
Asterisk). So it doesn't seem to be a problem of hardware. But we still
haven't figured out how to fix it.

One note as to Ethernet cards, we actually fried a Realtek 8139 Ethernet
card that we had put in a server temporarily as we were doing our testing.
It started to generate a lot of errors and dropping packets left and right.
When we took it out it was VERY hot. We then put in a 3com 905 card and
haven't had an issue with it yet.

Hope this helps,

MATT---

Thanks, Matt !

So, am I correct in assuming that there are quite a few (or alot) of us who
have had not so good experiences with Asterisk? That Asterisk would crash
after it hit a certain number of calls or after a certain period of time
with 15-20 calls? I understand that there were others who were able to send
a good number of calls through but can anyone tell us if they have had
tested and confirmed that Asterisk runs better without or with HT and in
terms of number of calls, how many would each one support, in the ballpark?
It would also be nice if one could tell us the computer configuration in
order to send that many calls without crashing Asterisk. Does it make a
difference running the LAN on a ONBOARD LAN card as compared to a PCI Intel
or 3COM LAN card, since there is a chance that packets are passing more
efficiently on a PCI LAN card?

Side question: Is it possible to do passthrough faxing? Like, customers
sending me H323 or SIP fax calls and the Asterisk will pass through to
another gateway? Anyone successful in doing that?

Tommy

Hello,

I've had Asterisk installed on HT capable machines in both HT mode(with SMP)
and non HT mode (with non-SMP) and did not notice any differences
functionally between them. The processor load was always less in HT SMP mode
than non HT and I have experienced Asterisk deadlocks in both modes so it
doesn't really seem to matter if you leave HT on(at least in my
experiences).

HT basically works by splitting off commands to one of two different virtual
processors that both run at about 70% of processor's speed(that's why you
may notice compiling to take longer when in HT mode) I have heard of some
applications having memory addressing errors with HT but I have not seen any
evidence to support that in Asterisk thus far.

I'm going to try installing a 4 x T1 card on my Athlon 2xMP server next week
and see if Asterisk/Digium performance/compatibility improves over the Intel
platform.

I have read before that HT did not help Asterisk so should be dissabled,
but as the chipsets and other hardware get better at using and
controlling HT it may help..

Run some tests on your system and see what your conclusions are, then
feedback your findings to the list so that others may learn from it..

Later..
