No. But it’s getting there. In business continuity we used to be advised to keep a POTS (plain old telephone service) line around because it would the last service to go down and the first one to come up. About a year ago we were advised that we shouldn’t bother. The copper lines convert to VOIP at a switch station.

Depends on where you live, I believe. But I imagine there would be some VoIP at some point if you’re calling any significant distance.

Even cell carriers in the American midwest have mostly switched over. I think partly because maintaining the infrastructure for traditional tech is costly, and VoIP has potential for higher-quality sound.
