Phones like this have been used for all sorts of things in Canada. 30-40 years ago some hospitals had these in the lobby and when picked up they just automatically connected to a cab company for people needing a taxi. I have also seen them in a couple houses where a small town volunteer fire chief lived and they just made a direct connection to the fire hall, somewhat like an intercom but using the telephone company’s switching equipment to make the connection between places.
