Implementation and Analysis of VoIP application

Abstract

Voice over Internet Protocol (VoIP) is one of the quickest developing Internet services and steadily replaces traditional telephony. VoIP application provides a means of transmitting voice communication over an IP based network and transmit voice conversations over an internal or external data network using IP packets (digital form) without reducing its functional, and reliability. This system illustrates how VoIP server uses SIP protocol and IAX2 protocols in VoIP applications. Moreover, this system applies VoIP application in small enterprise like UCSY (Hlawgar) campus and it analyzes call information between different sites. In this system, Asterisk open source server is used to implement VoIP application and an analysis system of that VoIP application is implemented by using Java.
