I just got a call from this number. When I picked up the phone and said "hello", there was silence at the other end. I have read where some think this would be just testing to see if a phone number was active or not, so it could be sold to companies of different types so they can do telemarketing calls. I do get quite a number of unwanted telemarketing callers every year --- so much for putting my number in the national "DO NOT CALL" directory!!

229-740-4468 called my cell this morning, leaving no voice message.  Strongly suspect scam robocall.
