Hey.... Im not sure what numbers you have to dial but you can have all your calls forwarded to another number... Possibly even a cell phone number but definatly a land line.... My dad was in the process of moving his buisness and had to have all the calls directed to our house number for a few days
I dont know how but a couple times since then (i think twice) someone hit the wrong numbers on the phone and all our calls were going to another place.. Just a thought.
