I'm sure that there are many telephone marketing organisations that get one group of people to research names of suitable targets, then another group to actually make the calls. Reason I think this is that, one day, someone rang my office number and asked to be put through to Mr Hawhouse (I presume that's what the researcher playfully entered onto the call-list). After this confident opening line, the pause was so pronounced you could almost sense the cog-wheels going round in this guy's mind. I think (this was year's ago now) my response was along the lines of "You're selling something, right? How do you think you're doing so far?"
