AT&T also has the feature of screening phone calls. You have 20 numbers you can enter in that are family and so forth that you want to have call you. Any numbers that are not on the list will be rejected and are told "the number you have dialed, doesn't accept your calls" This works out great on my end. Since Portfolio Recovery calls my house phone several times a day looking for someone who has NEVER lived here. And I can tell they are robo dialed phone numbers, since they call from same number 1 day and the next day it's a different number. They aren't worth my time. I have my family and close friends on my screening list anyone else like a Drs office I give them my Cell number to call.
