answer:No way this will work. landlines are just that, landlines. they operate similar to cable lines. a cellphone works in a competely different manner. cellphones send their signals to a nearby tower and the tower transmits your conversation to a satelitte. we abandoned our landline two years ago and have never regretted it. we upped our cellphone minutes and this just about evened out the difference. you can make a cellphone call to a landline phone and vice versa, but, this too, involves satelittes and not landlines directly. Put your cellphone in your pocket and carrying it with you throughout your house. this is why they call a cellphone a “mobile phone”. wife and i consider our cellphones to be like a third arm. it goes where we go.
