 Yes... the cisco uses SIP, that is far more efficient...

 i forget to say - SIP allows direct calls (data goes directly between 
 phones), SCCP doesn't (at least asterisk module).

 in tests i intentionally disabled this to make asterisk server loaded
 
 we use sip the same way you do with sccp because we need tranfer calls
 (,Tt) in the dial command
 E1 boards, the best we tested are from the chinese openvox... 
 without echo cancelation it seels for about U$750,00 for one port E1,
 US$1800 for 2 ports, 
 US$2800 for 4 ports...

My god, for the hardware involved, that's unbelieveably expansive.

 in my country (brazil) you may think it is too expensive, but as
 you 
 think that ONE port for a siemens pabx is about US$4000  (yes, 4K
 dollars)

For the Siemens pabx, you're paying for the switching capability, and the
literal ton of software to do all of the call handling.  Maybe I got you wrong,
in what I read above, I haven't seen those Openvox cards, but if they are only
voice interface (a T1 or E1 single channel) plus signally, wow, that's a lot.
If the interface an entire group, either T1 or E1, that's better, but it sure
includes a healthy kick for a profit factor.  I know, I've built them in the
past, there's just not THAT much to them.

Maybe I'm missing something.

Actually, in the present case, the cost of doing switching has dropped in a
major way, so the cost, which used to be justifiable at $4k/channel, well, it's
certainly not that way any more.

Let's see, from memory, I think that the old Northern Telecom DMS250 ran about
2.5 million plus the cost of channel banks, I think.  I was always doing
engineering,  not sales, but your cost figures, they sure do seem high to me.

As far as handling the software, the old tandem switches used to use
mini-computers to run maybe 4,000 channels in one switch.  I forget the name of
the most famous tandem switch, but I do know they used a single mini.  Today's
computers are far more capable, and so could very easily power a whole switch.
Course, doing that kind of software, well, it's the most difficult stuff to do
that has ever been accomplished.  The folks that did it never got enough credit.


 you may imagine that for the price of only one board for a siemens you
 can mount
 the pbx, the cpu, the FreeBSD.
 
 you mount a 100 phones pbx for less than half the price of a siemens
 equipment
 including the 50 ATAs linksys pap2.
 
 The poor the country, the more you pay  that is the rule.
 
 Philips, nortel, alcatel are even more expensive..

I have here asterisk (from the port) running with 2 ISDN cards (HFC) 
using ISDN4BSD with capi.

The computer makes the connections from
external ISDN, SIP, IAX2 - internal ISDN, SIP, IAX2.

Works for more then 2 years absolutly stable.

Best regards,
Matthias

I work on a copany that does this

PABX (large ones) only using FreeBSD - http://www.levier.com.br

FreeBSD 7.0 asterisk 1.4 openvox hardware
it is incredible stable...  and using postgres as a database + dial
controller...
(the dial logic is done in sql stored procedures) the possibilities are
far beyond
the needs of the clients

We have several call centers using it... in a 24/7 basis... 
Using hardware from openvox (E1/ISDN) 

How much cpu
we use always AMD 64 X2 with 2Gb of memory for
up to 3 PCI boards of 4 E1 each, that is: 12 E1.
Each board trigges 2000 interrups/second... so
there are 6000 irqs/sec on the system
for an universe of 200 ATA's  (cisco PAP2...)  and 400 users...
on line, fulltime... 

On the bench mark, FreeBSD was superior performance over
other OS... including the new Linux kernels.. 

The asterisk  is 1.4.20 build from the ports with codec negotiation
disable

Hope you have an idea now

what codec do you use? if no recoding (alaw) i think it uses very

We use ulaw (for the logarithm mode of the volume) so no recoding is done...


each board fires 2 irqs and 1000 irq/sec each...  so is 2000 irq per
board,
at a max of 6000 irq /sec

Cpu use (using top) is about 10%  only when receiving fax (because of
the spandsp), goes to 20%... when recieving 4 simultaneous fax

We use Hylafax  + iaxmodem...  works like a charm... the same way

As well as the ever popular Asterisk, there is also

/usr/ports/net/sipxpbx

If all you want is SIP this will do nicely.

Yes... the cisco uses SIP, that is far more efficient...

the problem is the E1 boards... that all the processing of hdc and
blocking/deblocking/signalling 
is done by the main board processor... so the high irq rate

We think FreeBSD is a good choice for VOIP asterisks... BEsides put us
(the company) in a higher
level.. not because Linux is bad, but because the linux people did not
made good servers in the past,
so, we decided to link our name (the company) to UNIX (BSD) it is a
