In the Auto Attendant screen, the admin creates actions triggered by single-digit numbers. When using the Auto Attendant, one should always be able to immediately dial an extension rather than an action. Therefore actions should not use numbers that overlap with the range of internal extensions. For example, if internal extensions are in the range 200-299, then "2" should not be mapped to an action. We should warn the user if they try to do this or perhaps simply exclude such numbers from the popup list of possible action numbers. (This suggestion came from today's review meeting.)
