Is it possible to send a cell phone call to my old land line phone which NO LONGER HAS A NUMBER associated with it. Basically I ditched my land line service (Panasonic KXTG7178 instruments ) but find my cell phone (Moto E4+) is always too far away. It does have Bluetooth and my former land line phones say they can pair with a bluetooth cell but the critical question is do I have to have land line service? Panasonic instructions tell me the cell must be near the Panasonic which leads me to think maybe it can be done. Zero electronics background so really in the dark and would appreciate enlightenment?
