Yes I did this and it works great!!!! Who needs the Do Not Call List. Wal Mart has the Panasonic phone that can block 250 numbers and came with 2 additional cordless phones for under $100.00. You have to it order on-line. You have to program it so it doesn't ring on the first ring to ID the phone number that is calling you. And no more annoying/unwanted phone calls!!!!
Got a call from this number, not the first time. I answered, they said, "Are you one of the mil . . . " I hung up.
This is what I see on my caller ID: Customer Care - 203-538-0971
