Flashdealer asked:


I’m pretty sure everything is now out-of-band and digital but I was curious to see if there was a far remote part of America or even North America that still use the old in-band telephone system or even an ancient crossbar system.

Additional, if the are no longer any in-band systems operating in America, I would be very curious to figure out when / where the last operational phone system of this nature shut down.
