Just called me on my work phone. I answered but no one responded. I didn't hear any noise on the line and no response after a couple of inquiries so I hung up.
They called me while on campus, did not answer and was going to call them back figuring it was a friend, now since I looked it up I thank this website!
They called via roto dialer - I answered and a southern woman tried to sell me a security system. She abruptly hung up after I tried to ID her company.
