Phone lister is an application used to manage corporate phone lists. Phone Lister can dramatically improve the speed of telephone extension retrieval for companies still using traditional time intensive paper-based solutions or limited in-house applications for phone list management. Phone Lister can be used by a single person or by an entire company sharing phone list data over their network. Phone Lister features an easy-to-use phone list display screen, searching and sorting functions and data import/export. Highly configurable, Phone Lister includes a user-customizable reporting feature.
