The driver from AVM only allows one Firtz card in a PC, there is a hack 
to run two but I don't know about 3.. Save yourself a lot of time and 
frustration and get a 4 BRI card from Eicon or AVM ( I believe the Eicon 
is better becasue it has echo cancellation but a little more expensive 
than the 4BRI AVM card) especially if its for an office install of that 
many users..

The GS phones are fine and work well, they have a few quirks but these 
should be fixed on the next firmware upgrade..

If you are running GS phones then the only codec availible to you is the 
G.711, using this codec you will not need all that powerful a server.. A 
1Ghz and above processor with 256+MB of RAM should be fine..

Later..
