10 hour voicemail


What the hell is this?
648 minutes, constantly repeating.

Quite a distinctive audio pattern.

Any clues?

    Is it dial up?

    Sounds rather like a pearl/blue box configured to walk through all possible DTMF frequency ranges, looking for something exploitable.

    Sounds like a blue/pearl box, potentially, configured to walk through all possible DTMF combos to scan for vulnerabilities in PSTN systems...

    When the tone stops, it means the nukes have gone off.

    I got something that sounds like that once when I'd messed up the config on an isdn trunk. Too long ago to remember the specifics but I do remember the sound

    I think that's called dubstep.
