Called my DNC registered landline, I picked up and said hello. After a brief pause a recording began about timeshares. I believe its one of those we buy your timeshare scams. The caller ID displayed the number 850-893-3991 and "Florida Call". A Google search returned no matches to any legitimate business, but did find white-pages matches to a local name and address. I believe they are spoofing local numbers in an attempt to increase the pick ups to their robo scam sales call.
