Got a phone call. No message left.

Two calls received within an hour on 7/14/2016 - No message left, but on the 2nd call, I could clearly hear the sounds of a boiler room/telemarketing operation. The caller said, "Hello..." but then hung up.

Another South Carolina call from unknown with no message. Know no one in S.C. Will block.

Telemarketer. I didn't answer, but on the message that they left, there was a lot of background noise, as if this person was seated in a large room with other callers. Blocked the number.

I don't answer calls from unknown callers.  That was the case here.  This caller hung up after three rings without leaving a message.

Previous experience suggests this is not the modus operandi of legitimate callers on behalf of genuine businesses.

Therefore, I am lead to conclude that the may in fact have been yet another round in the never ending game of "Scumbag Phone-tag".
