I was called by this number.  The man started to try to sell me a "wireless security service."  The call was from a VT number, but I don't live in VT anymore so I told him that and started to ask to be taken off the list when he abruptly hung up.  I tried to call back, but was unable to reach a representative, and the recorded voice sounded like the man I had just spoken to.  It's all very fishy and I think it is a scam.
