A man with a heavy accent wanted to schedule an appointment with a particular manager in order to make a presentation.  He claimed to have "a long-standing (15-year) relationship" with our firm.  Since I could barely understand him, I asked him to spell his name and that of his company.  He hesitated and said, "Aren't you going to connect me?"  When I replied that managers' calls must be screened, he decided to email the manager, instead.  If he really were an approved vendor, he'd have his contact's phone and dial it directly.  I researched the number on Caller ID and found a market research organization named TechnoMetrica in New Jersey.

I just got a call from this number. I'm not a business and they called my personal phone # how the hell is this?

They called my home phone last night at three minutes to nine. This doesn't sound like a legitimate company to me. Since I've learned to never answer unknown callers, I don't know what kind of nonsense I would have heard. Nothing legitimate, I'm sure of that The caller ID said Technometrica.

From search engine results, Technometrica appears to be a long-existing business :

I hands-on direct the highly respected TIPP Poll for Investor's Business Daily and The Christian Science Monitor. TIPP was the most accurate pollster calling both the 2004 and 2008 U.S. presidential elections. According to a New York Times analysis TIPP was the most accurate in 2012.
