This number calls me at least once a day and never leaves a message.  Today I answered and there was no one there.  I immediately got a call back and the person sounded like a recording...like a computer program that spoke what was typed (lots of words mispronounced).

I told the caller that I wasn't who they were looking for (company to garbled to tell what it was for) and they said they wanted to confirm my email address to send me a white.pay.a.per.

These are marketing calls from legit technology companies, regarding IT stuff.  Just tell them that they incorrectly have your phone number and it will be removed.

What a bunch of pushy ice-holes.

Got this call last month and several times before that.  Same nonsense.  Want to confirm email address to send out some sort of whitepaper from IBM.

Told them in the past that I wasn't interested but they keep calling.  This time I swore at the guy in language that made it very clear that I didn't want to hear from them again.

Come March, they'll call again.

I received a call (unanswered) on my cellphone from this number. They left no voicemail. This number will be blocked.

Overseas caller asking for employee who worked here 7 years ago. Often that means "free trade publication" subscriptions. Caller was very polite when informed the person no longer works here.
