Got this on the machine today. It sounded like a machine running or air blowing, for 4 seconds and then an audible beep and it hung up. Almost like data or maybe someone had a really poor connection.
The answering machine caught the "caller" saying rudely: "What is it with answering machines today!" before they hung up.
