Price of BRI .vs. PRI .vs. Analog .vs. Channelized T-1 vary DRASTICALLY
depending on your location and phone company.

Don't use FXO cards at all. Just convert your lines into ISDN. Isdn cards
are cheaper and has more features. Any ISDN card that is supperted by isdn4linux
must work, but I recommend you "Sedlbauer" chipset based.
Digium FXS cards are great.

Management is great. Reability is great too. The is some issues only with
h.323, proprietary codecs...., but if you don't use h.323 and/or g.729 codec
everything is great. Performance? It depends of what are you doing.
But sub $200 ebay machine (brand pentoium 3 1G 256 Ram) is enough.
I running it under IBM 266 Pentium II/48MB with 4 ISDN channels (2 cards), 1
LineJack, some
incomming SIP calls from Cisco AS5350. For FXS(office phones) I use 1 Ata 186, 2
Audicodes FXO gateway (4 ports)
and several PCs with gnophone and headsets. No problems at
all.

Only configuring a kernel to get ztdummy.o module running (for MoH and
conference).
Call queues works great. Only you need little hacking to get information from
call queues to the agents.
(Agents a brainless peaples by default and it is hard to understand anything
from text terminal :)).
If you wonna make bigger call center, just get T1 Trunk.
