Thanks to all of you for posting - I just got the call today as well.  When asked what this was about he said "business".  I said, "really?  Well, this is a business and I want to know what your business with my boss is".  Said he'd call back - I told him not to bother, he wasn't going to talk to anyone.  Thing is, my boss does like to talk with telemarketers sometimes.  And our company has telemarketers so we get that it's a necessary evil.  Had he seemed even a tiny fraction of honest, he might have gotten through.....but not now.  Not ever.
