I am looking to make a home VOIP network for a lab and was wondering what types of interface cards I would be needing to pull this off with an analog phone line. Any help would be great.
Thanks!

If you would like to start with an analogue phone typically this would mean:
FXS port - typically would allow you to connect an analogue phone to it FXO port - various ways to use this but typically acts like the CO to extend connectivity to a remote site (from memory) E&M - typically used to trunk between PBX's
Do a search on Cisco for FXS, FXO or E&M cards.
IMHO may be an idea to grab a copy of Dynamips and Google around for some voice labs. When you understand basic VoIP, dial peers, session targets etc then build on this and purchase a couple of routers and connect an FXS port into either with a normal POTS phone in each.

The VOIP cards are plentiful, and require lots of different combinations to work correctly.
You probably will want to work up to doing CCME. It might just be easier to buy a CCME lab setup from eBay with either a 26x1XM or 2811 with all the cards, DSPs, etc. you need.
Probably a couple FXO ports and maybe a FXS port to begin with, and cisco phones.
You can add onto that with more gateways later for more voice gateway stuff.
