There is a single port FXO from Cisco/Linksys (http://www.amazon.com/Cisco-SPA3102...3?ie=UTF8&s=electronics&qid=1230750527&sr=8-3). It's $73 from Amazon. This looks like it's a neat little box. I think I'm going to order one to play with it.I'll have to do some searching to find out if there is a single instance use of an FXO interface. The reason why I know a little about this is because I've been playing with VoIP and have done the second option. The card I purchased was a I think a Digium TDM 400. It looks like Digium has a new card out now which is a TDM 410. The problem with this card is that it's meant to work in a PBX/call manager environment. So you'll have to build a workstation/server type box with this card running in it. The system you can use is either Asterisk or Trixbox which is an open source freeware PBX software. Be warned though, Asterisk/Trixbox has a pretty steep learning curve. There are a few books out there written on just configuring Asterisk/Trixbox. You'll also find some good online resources. I hope I have the name right, but Keith Garrison has some online videos on how to configure Trixbox. Once you have the call manager set up, you can get a free software SIP phone like X-Lite which you then load on your computer as a phone extension. The software SIP phone when configured reaches out to the call manager and registers itself with it. I've done some in home testing where I've been able to make calls and receive calls via my Trixbox setup. The card was $130 at the time and the PC I used was just an extra box I had laying around.
I went down this path because I have an unlimited call plan with my Telco where I can call anywhere in the US for a flat rate. My thought was to open the necessary ports on my firewall to allow me to remotely connect up to my call manager and make/receive calls like I'm at home. I have a Sprint Air Card which I use when I'm away from home which gives me internet on the go. The use of my Sprint card doesn't incur a per minute charge so I can reduce the usage of my cell phone and stay at the very basic calling plan to save some money. Also, Asterisk/Trixbox has some other unique functions like music on hold, call forwarding, call hunting (where the call manager will dial the first extension you program in and if you don't answer there after a set period will call the next extension ultimately putting the call to your voice mail if you don't pick up), voice mail with wav file emailing so you can get voice mail via email, etc, etc.
I haven't played with the setup for a while as I've been working on bringing up a Cisco Call Manager Express/Unity Communications Express setup which will mimic what I've done with the Asterisk/Trixbox setup.
