If you are in the U.S. (you give no indication) then you must have your circuit approved by the FCC or use an already approved device to connect to the telephone network. Cute home-made circuits that might work will be illegal - especially if you plan on selling them (I went to your website)

You can find lots of illegal circuits using google. Have you tried it?
