boxes to do the same thing. If they are only able to handle 30 ports,
then they need to get in gear - we commonly run 72-96 (3-4 T1s) through
one box - usually a 486/33 or 486/66 with 8MB. We use NT servers to
provide the database services.
I'm curious what sort of hardware they are working with - if it is
Dialogic cards, I'd like to get in touch, since we were thinking of
trying Linux. The problem there is that the UNIX drivers for Dialogic
are _much_ more expensive than the DOS drivers.
Though in this case, choice of OS isn't that big a deal, since the chief
advantage of DOS is that it establishes the network connections and then
essentially allows the app to become the OS.

and to fix them for us, since we have plenty of code to write without
worrying about the OS. OTOH, phone companies often have plenty of
people, so this is certainly YMMV.

also uses Linux and we both like it. It's a nice OS, and I'm sure more
people will use it commercially as it keeps getting better.
I wonder how good a firewall it would make...
