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.. > > ___ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "[EMAIL PROTECTED]" -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.4 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFIXpYvz62J6PPcoOkRAsZoAKCDFT6zyX43pSZkSDC1xv3xsYsMXACfZQvq TsB0dr9vQN6+03TVyGl9mA0= =oUqG -END PGP SIGNATURE- ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

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 24/7... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

If so, what software 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...

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.
