Another Reason Google Is Likely to Win...
Gordon's Tech:
Technology defeats the do not call list: 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.
