Caller ID shows Florida origin. No message left and busy signal upon calling number anonymously. I tend to agree with "Death To Twelemarketer's" Sept 9, 2013 input that it originated about a Disney vacation. Many companies have no respect for the DNC Registry.
I use phone.com as my telephone provider instead of ATT. This low cost service has call blocking as well as lots of other features with good quality sound. I don't have any connection with the phone.com firm but it saves tons of repeat calls from telemarketers. As an example in last two weeks 5 calls have been blocked YEAH!
You can't be serious. *57 might generate a trace, bit it doesn't report it to anyone, much less the FBI. You would have to jump thru hoops, getting your phone company to send the trace to your local police, WHO WOULD IGNORE IT because they have better things to do. Give up. Get a phone with call block. No one takes these calls seriously except you and I only check the numbers online to make sure they really are scammers.
