Hardware to implement Asterisk server

Hi all,

I’m new in Asterisk i have some description to a VoIP solution in my job :

 Plate-forme modulaire;
 2 interfaces Gigabit 10/100/1000 ;
 card (1) primary access (T1) ;
 8 PSTN access interfaces ;
 150 users supported;

i don’t have any idea about hardware where i’ll implement the asterisk server
some one can helps me here?
Thanks in advance

That sounds like a good start. Add a fast CPU with a bunch of RAM. Maybe make 2 machines so you have a backup plan.
