not rocket science. Every motherboard can handle 3 PCI cards, not rocket 
science. As far as a load - since OP stated there are only 24 calls in 
progress - only 48 concurrent channels will be used. It doesn't need to be 
all that beefy hardware.

I beg to differ. Channel banks are a dime a dozen (500$ ish), quad cards 
are 1500$ish list, complete setup 500*9+1500*3=9000$. Replacing phones 
with IP phones is at least 125$ for not-completely-ghetto-phone each - 
meaning at least 25k$ for the phones, not to mention necessary rewiring 
from cat1 to cat5.

Again, not rocket science.
