This one is interesting. I've received several calls from this number that I don't answer. No message left. Yesterday, I received a call with the caller ID of "Desai, R." but with a number other than this one. Today I received a call with the caller ID of "Desai, R." and this phone number. There's information in florida about a scam that is being run in which so called "energy savers" tell you that they are a non profit organization with authority from the local energy companies to do an energy audit on your house. The energy companies have never heard of them. One report says if you schedule such an appointment they might or might not show up. If they do, they do some kind of phony "energy audit" and then try to sell you some trumped up service to reduce your costs. White pages directory says this number is a cell phone. No real company is going to be using cell phones. I think they are trying to get around the Do Not Call regulation by pretending to be an energy audit service. Here is the link to the DNC site to complain and a link to the Florida site that talks about phone scams.
