I have received multiple calls from 706-208-8816.  When I answered the most recent one, there was no response for a couple of seconds (often a sign of a robocall), and then a person with a slight foreign accent came on the line.  He asked me first about my state of residence and then about my income/wealth.  I told him I didn't give out such information and hung up.  Don't know what his game was.  I have now blocked the number.
