This is maybe an insane question but do some people still have beepers/pagers?
@sonicbooming They are still around but increasingly rare. Within hospitals, I’ve seen more places with what are basically big private cordless phone systems rather than pagers. They are like partway between a DECT cordless you’d have at home and a cellular. You can page and also make/receive calls within the building. I assume there is a sign-in/assign procedure to map people to phone handsets somehow.
