Don't call 888-556-7682 or 877-646-7319. They are "you confirmed your real number, sucker" numbers.
Scammer number collectors post these numbers on these phone number websites.

Recieved a call from 205-572-4898, Birminghamm, AL at 2:56 pm on 06/30/11. Did not leave a message and I do not know who this is. My number is on the Natinal Do-not-call listing for several months.
