[Asterisk-Users] hardware compatibility

[kemal asad]

I am setting up my soho, am treating myself with some new and cool
hardware but before i go crazy on these new gadgets i wanted to check if
my idea made sense. i wanted to get http://openbrick.org/ as a router to
connect my office to adsl . then on a computer with the following
motherboard

 behing the firewall router i would put if compatible  :

i am not sure i understand what asterisk is all about but i guess i will
need to get some special handset. if you have any suggestion please
advise.
Thanks.
