Directory Features in a Distributed Telephony System

A telephony system is presented that enables a phone to access a directory and use the directory in conjunction with other phone functions. The system includes a server with a telephony management software (TMS) unit, a telephony application programming interface (TAPI) unit, and an application unit. The application unit includes a control module, a function module, a filter module, a presentation module, a phone interface module, and a storage interface module. A server sends a signal to a phone regarding the contents of a directory. A server also enables a user to navigate through the directory, filter the directory, and perform call functions on phone numbers associated with directory entries.
