In any sane set up, if the user fails to navigate the menu n times you get dumped to an operator. 0 or * or # aren’t special hacks, you just need invalid navigation.
I imagine what you have noticed is that increasingly there just isn’t an operator to talk to, or at least the org you’re calling really doesnt want to talk to you, so this kind of navigation failure just dumps you back to the start or something.
