Conferencing, Paging, Voice Mailing via Asterisk EPBX

This paper is intended to present theoretical and implementation details of various important features that are generally associated with an Asterisk based Voice Exchange i.e. Conferencing, Paging and Voice mailing. Besides this we will be concentrating on the web based approach for the configuration of the hard phones that will be used at the clients end. Our approach follows the client server model for all subsidiary procedures. The application is developed in C language and is compatible with all the versions of Linux, essentially providing PC to PC data and voice communications.
