Abstract

The drawback of EAPBX system is that it required extra wiring and the extensions are very difficult to manage. The solution to this problem is the use of Internet protocol which carries voice as a data called "Voice over Internet Protocol". The advantage of this system is that it uses the existing network connection installed for the organization and the management of the extensions are very easy as it can be manages from the web browser. The system is cost efficient as it uses only one computer system as a server with Linux based operating system called "trixbox". The system uses the USB handset as an interfacing device like telephone. General TermsVoice over Internet Protocol and Session Initiation Protocol i.e. SIP based client server system architecture is the base of the system. The System is compatible for LAN, MAN and WAN. This system also supports the Voice over WiFi Network if the organization consists of WiFi campus.
