Cell Phone/Landline Help...

I'm not exactly tech savvy so bare with me on this one...

I want to get rid of my landline at the house and my wife doesn't want to
because... she doesn't like to hold her "little" cell phone to her ear for that long :dunno:

anyway, is there such a contraption that you can set your cell phone into
a cradle and have it transfer the call to a remote phone? :scratch:

I'm not really confident in her ability to grasp the blue tooth concept and make it work so, a cradle/transfer would be my first choice...

does this make sense?:loco:
