You can put your cell number on the national do no call list no problem. I don't have mine on it yet, get an occasional call. The wired phone we have used to get alot of them and the no call list works great for that. I don't have caller ID at home but do on my cell of course, so I can just not answer the "ID Restricted" calls or numbers I don't recognize. They never leave a message, so hope it's not the "Publishers Clearinghouse" calling to tell me I won a million or something........
