This is a vague and unclear question.  You will need enough CPU power  
to handle whatever system design you choose.  There are internal  
cards (PCI) that could hook up the PSTN lines for you, or you could  
use external hardware (gateway) for that.

FXS's hook to phone hand sets (old school type).  FXOs hook to PSTN  
lines.  Your above description needs 8 FXO's and NO FXSs, presuming  
you use IP phones as extensions.

Hope this helps.
