Well, after bummin around thinking I had bad fxo cards, I finally discovered that I was loosing two phones in my home when I had the cards plugged in... Turns out the jack I had plugged into, was wired for two phones (line 1, green/red and line 2, yel/blk) and I also was using a 4 wire phone cord for the connection. It turns out that the x100p cards are wired in such a way internally that if you are running a 4 wire phone cord to them, that you might short out between the two lines at the jack (which worked separately with phones and computers) and get funky results..... Moral of the story is to always use two wire phone cords with the x100p fxo cards. Problem solved, and I was able to continue my development....
