I received a call shortly ago as well. Didn't answer, no msg. Annoying.

Received a call from this number today. Caller identified himself as Ohio State Trouper. Assuming it was a solicitation, I hung up. Then, fearing there was someone in trouble and needing me, I tried to call back. Got busy signal first time, and then a recording that the number was no longer in service

Called, no message left
