I have been getting calls from this same number (and others, playing the same game).  They ask me to transfer them to someone at my place of business.  I have explained many times that I am not the switchboard, because I'm pretty sure they're just trying to cold call someone at our company, and trying to use me as the first step in establishing their credibility.  It's not like it isn't REALLY EASY to find a direct phone number for EVERYONE to whom they ask me to transfer their call if they would just look on our flippin' web site.  It is APALLING that our telephone companies can't do anything about this kind of clearcut abuse.
