Re: Caller ID shows "Unavailab

Just spent over an hour discussing/complaining about the "Unavailable" "1" calls with about 4 AT&T reps. They all say the same thing, nothing they can do about it because they don't know what the number is to allow us to block it. Typical customer un-service response. Bottom line is they are probably making money on the situation so there is no compelling reason for them to do the right thing. I'm supposed to get a call back from a manager type. I'll repeat my request if/when they call, credit my account with a dollar for each one of these calls.
Your logic is so far out there. There are too many ways to spoof call blocking that most good hackers can do it. If you don't want to get those calls set up call screening. That way only the numbers you decide actually get through.
I found this out from here.
The phone company didn't pay for it therefore doesn't show up.
