Landline to wireless

A wireless home phone, there's several who have them AT&T's is called AT&T Phone Advanced. Verizon sells them and several resellers have them.

There's also cell to jack where your cell phone plugs into your home phone. 

Thank you.   What should I search when looking for the cell jack?  Cell jack?  The customer service representative told me what it was. But, I'm for the life of me I can't remember what she called the dean thing!

There's one that's called Cell2Jack, but I'm sure there's others.
