A-Best: your question is confusing..
you said you *73 (you many need to use 73#) from your land line.. deactivating call forwarding on your land line... so calls to your land line are ringing on your land line... that is what is supposed to happen..
if you canceled call forwarding then your cell is not going to ring when someone calls your land line..
if you wanted to activate call forwarding you need to call *72 (or 72#) then the number you want to forward to...
if you want to forward, or cancel forwarding on your cell phone then you will have to go thru the menus on your cell phone...
