SIP Visualizer and Its Security Aspects

Abstract

Today s era is totally dependent on the Communication technology. In newlinemobile life VOIP phones, 3G, NGN (Next generation Network) plays very important newlinerole in human life. VOIP phones are much cheaper than other phones. And VOIP newlinephones are based on new SIP signaling protocol. So our thesis is related to SIP. The newlinethesis deals with two sections, first section describe about SIP visualizer tool and newlinesecond section describe about the security analysis of SIP Visualizer. newlineSIP (Session Initiation protocol) Visualizer is related to telecom department. newlineThis tool has been designed for visualizing SIP call flows. It shows the status of the newlinecurrent messages, and also of the complete scenario that is taking place. With newlinevisualizer a user can see, how the messages are flowing from one user agent client to newlineanother user agent. newlineSIP visualizer is totally based on the SIP Protocol. The Session Initiation newlineprotocolis a new signaling protocol developed to setup, modify, and teardown newlinemultimedia sessions over the Internet. SIP Visualizer works where the user wants to newlineknow about his session and SIP messages to the corresponding session. It will work newlinein the call center s STF (special task force). It will be very effective in Telecom newlineCompany like Airtel, BSNL, Vodfone etc. newlineIn the security architecture of SIP Visualizer we have analyzed security of newlineSip Vis and proposed a solution for end to end system security. newline
