       Computer security peeps: does anyone know of a tool that would be like the POTS equivalent of "nmap -O"?  Meaning, if I have a random phone number, is there a way to identify what kind of phone picks up when I dial it?I suspect POTS is too dumb for this but we have geniuses everywhere and I haven't been surprised yet today.

       @paladin1 It seems as though that wouldn't work, because how would you tell? A telephone doesn't transmit any identifying information when it goes off-hook, it just starts drawing current.I'm also struggling to imagine how this information would be useful, but presumably you have an idea about that.

       @publiusYeah I expect you're correct. I had kind of wondered if someone had done some kind of acoustic analysis to determine if a remote headset could be identified. For smartphones I think this might be plausible, but for older dumb headsets probably not.It was mainly a thought experiment. Not sure if this would be useful at all, though I'm sure some social engineer or pentester would find a use for it. It's way out of my skillset to follow up on.
