The caller was a lady and got through to my extension. I asked her how she got my number and she said that she got it from Linkedin profile. she already knew my office email address and said that she is sending some info about travel promotion etc. I am suspicious but could not do anything since she already had my details.

BEWARE!!!! Received a call from this number for MY UNDERAGE SON to a phone number that was not in any relation to my son but the person who answered the call knew me and informed me. Has to be a SCAM if they are calling for underaged children!

Caller asked for a co-worker. She took the call and he asked her to confirmed her name and email address, which was her work email. He said something about U.S. Cellular and she said "no thank you." He then called back asking for another coworker, and I told him she doesn't work here anymore.

I, too, could hear conversations in the background, like a call center.

They just called my work phone, I wasn't able to answer and they didn't leave a message.

Just called my work number, twice, three minutes apart. I don't want your products, I don't want your whitepaper, I don't want a subscription to your journal, I don't want to learn more about your services, I have nothing to do with IT. Get a life.
