<h3><a name="#dp2008-01">2008/01: VoIP application development using SIP protocol</a></h3>
<h4>D. Milic, D. Zhou and H. Situ</h4>

<p>This aim of this project was to the explore JAIN SLEE standard 1.1 programming model and SIMPLE (Sip for Instant Messaging and Presence Leveraging Extensions)  protocols, developing a Voice over Internet Protocol (VoIP) application with functions that include making a phone call, instant messaging to peers, and at the same time providing users with buddy list information of their peers.  The JAIN SLEE platform RhinoSDK 2.0 (developed by OpenCloud) was to be used and an example application that is included with RhinoSDK 2.0 was to be extended.  During the project the phone call functionality was scoped out of the project and the focus was set on implementing the instant messaging and presence functionality.  This report describes the functions that have been implemented on the server side and client side of this VoIP application.</p>

<h3><a name="#dp2008-02">2008/02: Report of Otago contributions to Telecom LifeLink Project</a></h3>
<h4>N. Lewis, H. Situ and M. Middlemiss</h4>

<p>Gartner has for some time been reporting the potential for virtual world technology to become the next wave of the Internet, delivering what is known as the Web3.D environment.  This is characterised by a high level of user participation through immersion in the virtual world. Gartner has predicted that by 2011, 80% of internet users will be regular users of Web3.D technology.</p>

<p>Project LifeLink was initiated to discover what opportunities for Telecom might exist in the growth of business and consumer interest in virtual worlds. This has focused on a number of technologies, in particular Second Life, OpenSimulator (OpenSIM) and JAIN SLEE. The project has been run by Telecom with coordination and support from MediaLab, and with researchers at Canterbury and Otago Universities. This report describes the work undertaken at Otago University to implement a gateway to enable demonstration of communications between an object in Second Life and the JAIN SLEE environment in order to interoperate with external network services.</p>
