Received a call from this number today and shunted it to voicemail. No message was left, so (after checking here) I blocked the number using my Android call blocker. End of problem.

This is just another fake number looking to scam you out of money. I have noticed I am getting random calls every single day with different numbers supposedly from different states. I guess this is their tactic to get around call blocking features. Anyway the call was about making money from home. They had called two days before using another fake number supposedly from Florida.
