Dear 100 Hour Board,
On TV shows and movies, whenever someone hangs up the phone after a telephone call, the line almost always goes back to a dial-tone, and usually immediately. In reality, if you listen to your phone after the other party hangs up, it usually remains silent for a little while and then goes to a busy tone, never back to a dial tone. Why?
- Slick Rick
Editors of movies and television programs try to get the point across as succinctly as possible. They just want to show on screen that the person has been hung up on, so they hear the immediate tone instead of listening for three minutes of dead silence, followed by that extremely annoying busy signal.
