"Thank you for calling XYZ Company. If you want to reach our dial by name directory, please press the "#" key....Please enter the first three or four letters of the person's first or last name..." "No. I dont want to try that." - this is common reaction when I come across the dial-by-name directory feature in business pbx systems.Most people hate it anyways, for a long list of reasons which I won't bother listing. But one of the latest reasons to drop this feature, completely, is the popularity of smart phones.
