What you will need to do is to set up a new account for the home phone. Don't get the number ported into your existing Fongo number as it will replace it.
Personally what I would do is sign up for Fongo Home Phone and make sure it all works, then port in my number. I know you will be saving $5 by doing it all in one shot, but I would rather not have the hassle of having to port my number back out again if it turns out it isn't what I want. The chances are you will love it and wonder why you have not done it before, but you never know.
As long as you set up a new account when signing up for your Home Phone, your existing Fongo app number shouldn't come into play.
