Same.  The callerId showed "Out of Area".  Seriously, in this day and age, who in their right mind would pick up?  If you're up-front, provide an honest description of yourself or your service.  If not, you're screaming "fraudster".  Now that I think about it, transmitting your web address with an actual brief message being left would probably work better.
