> 11 Calls were answered with only music. The music could indicate something, such as being in queue for some service. All music variants except for one sounded like generic elevator music that could be the default hold music in PBXs. Someone told me that there used to be actual phone lines playing music 24/7 that elevators would dial and output to a speaker. Speaking of elevators, their emergency lines are also usually just phones and, as someone already pointed out in this thread, with enough knowledge you can call the elevator and listen (and talk) to people in it.
