OK, but do you really want to go back to paying the current equivalent $10 per minute for the privilege of using a piece of dedicated copper for a cross-country call?
BTW, "nine 9s" is one just second downtime out of 30 years continuous service. I was there back in the day of analog long distance, and I can assure you that reliability was nowhere near that. For example, if you tried to make a call on Mother's day after dinner, your chances of actually getting through were often less than 50%.
Getting a "fast busy signal" when you picked up the phone was also a thing that happened at a couple of other random times per year for no apparent reason. I hate to admit it, but my current VoIP service piped over the crappy cable company's coax is probably just as reliable as our POTS line was 50 or 60 years ago.
