I received a call twice from this number. One on my work cell phone and then on the personal cell phone. It was offering a sweepstakes offer that I entered some contest [I don't enter contests], and these telemarketers are getting even craftier because it is an automatic voice. When you pick up, they say, "Hello?" Then they expect that you said hello and respond with, "I'm sorry about that, I was adjusting my headset." From the other call, it was a guy's voice and he said, "Hello?" But I purposely didn't say anything to see if he would respond and he did with, "How are you?" and started with the same pitch as the woman who said "I was just adjusting my headset." These automated messages are getting so crafty to trick you into thinking that they are real because it is a human voice but it's not voice prompted.
