I've been getting repeated calls from 459-121-8344. There are web reports on this number, it's supposedly a telemarketer scam.
AT&T will block this number -- for about $6 a month. I tried reporting it as a violation of the do-not-call registry but of course 459 isn't a real area code (it's spoofed). So it can't be reported.
Google Voice will block these numbers.
I suppose if the problem continues I'll have to port my mobile number to GV.
I got several more calls, and I tried AT&T support (611). The representative estimates AT&T is getting about 20,000 complaints a week. So the pressure is building for them to provide a free version of the $5/month 'smart limits' call blocking service. He recommended one of those paper things with stamps on them sent to:
AT&T Customer ServiceBe polite, do mention that you're on the do-not-call list (even though cell phones shouldn't need to be added, add your number anyway), and request that AT&T provide free call blocking similar to the smart limits service.
