Taped message warned of potential dire actions if I didn't call this number back in order to find out about something or other regarding taxes or some such. Patently obvious scam covered by one extra layer of deviousness by requiring recipient of message to continue contact by calling back. Really tempted to do that just for fun but well aware that my phone number would then be considered "good" for future such nonsense. Reverse check on this number shows it's a mobile number carried through YMax Communications of Jackson, Tennessee.
