Only the number shows up on CID and no there are no useful Google hits on it.  Caller will not say where they are from/who they are with.  They've been calling for an employee for a couple of years "to serve papers on him" unless they can get something straightened out.  This is a scam of some kind as we have never produced the employee for them at which point they threaten to show up with "the sheriff" only if it was legitimate, they would do so and never have.  I've told them to stop their foolishness and bring the sheriff, yet they never have.  So many scams, so little patience for them.
