Caller ID said "Leesburg," a nearby town in Virginia.  Caller, who had an Indian or similar accent, asked for me by name, provided his name and stated that he was calling on behalf of something like "Health Services Survey" or similar.  Caller was using some kind of robo dialer given the time it took for him to come on line.   Could be legit, but why bother given the number of scammers out there?  Hung up.
