Menu Control catch all
I'm using a menu control, and I have all of my menu options setup fine, however is there a wild card option so that if someone types an invalid menu option they're not just taken to a dead call and it can be handled a little more gracefully? (like "?")
I noticed I can loop back (i.e. dial zero to hear this menu again), however I'm trying to determine how to handle menu options which are invalid more gracefully.
