Robocall telemarketer. Did not find out what the scam is.
I said hello and it clicked connected and I heard call center background noise and a voice, then disconnected.
2/14/17 12:52 PST Tried to call just now, but didn't answer because don't know the number and ID was unknown. No message was left so probability is telemarketer or some other undesirable. If they try again, will block number.
