I also have had calls from this number over the last week or so. On the 6th my workplace sent this:
"October 6, 2009
*** FYI – cell phone numbers go public this month. To keep from having your number released to telemarketing and sales companies, you may want to call the following number from your cell phone: 1-888-382-1222. It is the National Do Not Call List. It blocks your number for 5 years. You must call from the cell phone number you want to have blocked. "
The message about cell phone numbers going public has been circulating for about 10 yrs now. It's not true. In fact, I have my number listed and the calls actually seemed to increase. Don't know why I'm suddenly getting calls from Canadian numbers (2nd in the past 2 days!).
