How to install magicjack?

simply plug the magic jack into your high speed internet modem or router, or the USB port of your computer connected to high speed internet, depending on which model you have, and then plug the standard phone line from you telephone into the magic jack.

However, I have read somewhere that the magic jack can be jerry-rigged so that it works through existing phone lines and wall jacks, but I have not been able to find that method. Does anyone else know how to do this?
