In my town in the 1990s, it had the unique feature of a free local number you could dial and use to play games, get movie showtimes, find out the time, and more. It was almost like audio-only webpages you pulled up with a four digit code after initially dialing a regular phone number. I would spend lots of time on there, typing in random codes to see if I could find an Easter egg. And I did.
I found a code - I think it may have been 9876 - that opened up a service where you could leave a short message that the next person could hear. Frequently it was nothing much, but sometimes it was … pretty strange, sometimes pretty entertaining.
Did anyone else stumble upon this strange corner of phone service, where you left a recording for strangers, and listened to what they left?
