There is now a video game called Hello Operator that uses a real 1927 switchboard and let's you play as a telephone operator
In the video here, Kirk plays Hello, Operator while Mike explains what’s going on. You can’t hear it in the video, but Kirk is hearing pre-recorded voices on the phone as caller after caller asks him to connect them to a specific person identified on the switchboard. Kirk has to physically make the connections and then the call proceeds.
I think this is really cool.
