In Denmark there are no payphones. Like none. The copper network is being decommissioned.
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)
