Not directly on-topic, but dunno where else to post this.
I keep getting these strange messages on my answering machine. Now, I'm used to getting lots of annoying, irritating and even enraging messages (I owe big $$$ and am being hounded by collectors, plus I get the usual telemarketing bullshit).
But these messages are just plain puzzling:
"This message was intended to be received only by an answering machine. Thank you." CLICK. [dial tone]
They come at the rate of one or several per week. At first, I was totally puzzled by this: "OK, so what's the message? You left it on my damn *answering machine*!".
But now it occurs to me that perhaps it's not aware that it (the robo-caller) is talking to an answering machine. My machine is several years old--OK, older than that: more than 10 years old. But it goes "BEEP!" when it answers, just like any other answering machine.
Perhaps that "BEEP!" is not the correct frequency/amplitide/duration to be recognized as a valid answering machine?
