Comment on What are some of the impacts of a power outage that isn't that obvious / isn't talked about a lot? And What happens to restaurant bills? Do Buses still work? (since card payments wouldn't work)

In the US, telephone land lines actually carry their own DC electrical charge which is provided by the telephone central office and travels through copper wires to each phone.

This is why, during a power outage in the US, a land line phone will typically continue to work. The exception being if the outage is large enough to also take out the central phone office.
