No message.

Call back gets "Press 1 to connect your call."  No identification of company, no information, just the "press 1" instruction.  A legitimate company would identify themselves.  Block it.

Forgot to add this:  pressing 1 might result in your being "connected" to some overseas toll call.  There have been reports of such things leading to exorbitant charges on phone bill.  Best not to do that.
