"Melody Phone" was invented by Jean Georges A Mourra. My father was the first person who invented music while waiting on the phone. It's a music box that you attach to the back of the phone. My father invented it because everytime he was waiting on line for someone, they would hang up the telephone, and he got tired of waiting and then they would hang up on him. If anyone says they invented it, they are wrong. My father is still alive and he is 81 years old.
