A new twist on an old slimy way of getting through the switchboard.
Worst one I ever got as a call transferred to me where the individual claimed he was calling from the NOC at our ISP (by name so I imagine that he must have done a whois lookup).
Turned out to be a Cisco reseller cold calling slimeball. I asked to speak to his supervisor. He tried to BS his way out of it with a lame excuse and I informed him that my caller ID shows the number so if he chose to do something other than what I asked, I would call back and ask to speak with the CEO.
The nimrod's supervisor was very apologetic and assured me that we would not receive calls from them again.
