That's happening piecemeal in the US as well. Any "landline" phone service at this point will be coming from a box hooked up to your internet service, quite the flip from the old days of dialup internet.
Pulse dialing still works, and the automated voicemail system that the CO switch runs has zero perceptible latency (unfortunately, they won't give me the PIN to set it up)
Kudos for pulling all these into one database
