Report these to the FTC(Federal Trade Comission) The phone companies rarely do anything with the information, but the FTC can shut down the phone numbers.
I got the same call last night. I pressed one the first time just to see what it would do, then hung up when the next automated message came up. I'm contacting the FTC.
I just got the call, too, on my personal cell phone. Very annoying. I didn't answer it because of the strange area code. Guess the FTC still hasn't done anything about it.
