Well, I called the number, and listened to the whole spiel. Of course they already called me a few days ago and wrestled me into handing out their stupid cards (see Dejibo's thread). I guess that wasn't enough, they wanted to wake me up and then hang up on me.

At the end of the recorded stuff, there was the opportunity to enter my phone number in their "do not call" list, which I did. They promised that it would be removed "within 30 days". Thirty days?? I feel so supported.
