IP telephony service creation using SIP Servlet technology

Abstract

This Master's dissertation gives an overview of the new IP telephony signaling protocol---SIP and studies the different IP telephony service creation programming models based on SIP, such as SIP CGI and SIP Servlet. Then we note that SIP servlet is a rapid and efficient service creation programming models amongst others. Also studied are the possible ways of defining the SIP Servlet API and how it can be implemented together with the existing HTTP Serve out API and servlet engine. In addition, several prototypes are given to show how to use the SIP Servlet API to create the typical IP telephone services, such as, call forwarding, call waiting, etc.
