There is big difference between a TDM card and a USB device. Also were you
actively using all ~600 extensions at once?
The system we were building was a predictive dialer. Not only were all
channels engaged at one time but we were actively establishing and
disconnecting channels at a rate of over 15 per second.
Anyone who is looking for a DS3 TDM card is probably not looking to use it
to hookup channel banks with it. They are looking to increase their line
capacity, thus increasing their number of concurrent channels.

Our device is both a USB device and a TDM one. Analog vs. digital (or
extension vs. trunk) may be relevant. As for PCI vs. USB - they keep
telling us USB makes things more complicated

No. In those limited tests we made we got to ~200 FXS channels running.

While I don't have your experince, I would still speculate that even for
trunks the average capacity is not ther same load as that of a
predictive dialer.

The policy was put into place for a number of reasons, the main one being that
it's generally a good idea and is therefore pretty industry standard.

I used an Adtran MX2800 to break out 28 T1s (PRI D chan on fourth T1
using NFAS) per quad port server.
As for call setup, hearsay, is that Asterisk is very slow or not
capable of handling high volume call setups.
CallWeaver, forks, or whatever you want to call them are many times
better at setting up SIP calls per second than Asterisk.
I do not have the numbers, I only did inbound, but maybe someone could
elaborate on actual figures.

Oh, please, don't start THAT flame war. People who consider Reply-To
munging harmful have obviously failed to read the ENTIRE rfc (especially
the part where it specifically says the use of the Reply-To header is for use
on listservs).

Agreed; I've set these up and they are rock effing solid. We did have a shelf
controller die and without the backup shelf controller, we had our only DS3
down for several days... the replacement shelf controller was lost by UPS...
talk about a train wreck learning experience.
Ahh, the good old days...

Yes, I've seen that, and most of its arguments are specious, at best.
They amount to "I am too stupid to find a mail user agent with List
Reply, and too lazy to switch to it".

And the arguments on the other side come down to "I'm using an ISP
which can't correctly configure their mailserver, and I'm too lazy to set one
up myself." and "I'm too lazy to check the headers when I send out a reply."
