I got a call tonight too. looked it up....says it's a number owned by a telecommunications company.

Received call, no voicemail.  CID: Ohio csll

I called this number back and all I got was a HELLO? It just says Barnseville, OH.

Pretty much the same experience as others.  Caller left no message.  This is a suspicious call.  Number is possibly spoofed.  Legitimate callers leave messages.

Live voice said hello, then a recording came on thanking me for returning their call.  This is allegedly a number for the Ohio Highway Patrol fallen officer fund, they are seeking donations for wounded or slain policemen.  I hung up without listening to the entire message it is kind of long.
