Problem that telephony drag that SS7 with it regardless of used media. It was used on raw copper, digital data over fiber or radiowaves, now they use internet to run their SS7 rituals and looks like that mammoth shit will be used on any further tech.
F.e. it is obvious that today things like "roaming" or "interstate calls" have absolutely no any sense. But teiephonists still sticking to all that senseless crap for mo any technical reason.
If you are not aware, when you use your cellphone to make calls from outside of your "local area", your call routed through phone network via your "local area" phone switch, even if you on the other side of Earth calling to nearby restaraunt to reserve a table.
That's really so insane, that nobody could imagine all that crap telephonists still pracrticise. And that is why there are no any wonder that a single broken line could ruin some phone service for the whole country and even a world.
