[Asterisk-Users] Newbie setup (Hardware questions)

[Puddle]

Thanks, that makes a lot more sense.  Would VoIP
phones still require FXO units or would that not
require any special telephony hardware?

I'm looking to get the book VoIP Telephony with
Asterisk anyone have any reviews on this?

Thanks!
