Don't know about the software hooks to make it work, though.

The FXO/FXS equipment is needed if you want to connect an analog phone to your computer, OR you want you want to connect your computer to the PSTN (Plain Old Telephone Service, a.k.a. Public Switched Telephone System?). When you connect your computer to an analog phone line, your computer actually emulates a phone device. When you connect an analog phone to your computer, your computer emulates the phone company (produces dialtone, etc). An FXO card is the card you connect your computer to the phone company. An FXS card is line emulation done by your computer, that you connect your analog phone to. If you want to connect an IP-Phone to your ethernet network, and use asterisk to peer with some VoIP provider (like FWD using Asterisk's IAX2 peering protocol), you don't need any FXO/FXS hardware. Note, that some IP phones, since they talk SIP, can already talk with public SIP services, and you don't need Asterisk at all if you do not need operator capabilities.
