Also automatically recall silently, if the line timed out. Basically notify me when it got through to a human. Maybe record my interactions with automated systems and then offer me a dialog for a pre-fill next time. Would be a real, valuable edge for me. I hate spending life time in phone queues.
If it can really understand that hold music stopped to play a periodic voice recording of “your call is important to us” is still a recording (and not have the urge to smash phone at the wall) I’m completely sold!
