asterisk users - Jun 2005 - what hardware components do i need?

I have a Linux server, in which i will be installing asterisk 

and 

20 personal computers in LAN with full duplex soundcard, microphone(headset) 

and 

Internet Connection - DSL of speed 128kbps 

I will be using asterisk for making calls to PSTN numbers 

so what are the additional hardware components needed? 

suggestions please!

No additional hardware would be needed if you connect to a voip provider 
for your inbound/outbound calls.  If you want to plug phone lines or a 
PRI into your asterisk box directly, visit digium.com and have a look at 
the various PCI cards they offer.
