WeSIP is a SIP and HTTP Converged Application Server built on top of OpenSER!!!
WeSIP adds a J2EE layer to OpenSER so you can benefit from the existing OpenSER modules and features, which already implement nice functionality like registrar,nat traversal, diameter authentication or radius accounting at blazing speeds,while at the same time enjoying the ability to develop and deploy new converged SIP and HTTP applications in an J2EE environment.
Jiplet is short for Java SIP Servlet. The Jiplet Container is an open-source container for server-side SIP applications.
Project SailFin is based on robust and scalable SIP servlets technology on top of a deployment-quality, Java EE-based GlassFish. We are working towards achieving JSR 289 compatibility, adding high- availability and clustering features, and integrating with existing GlassFish services.
JSR 289 updates the SIP Servlets API and defines a standard application programming model to mix SIP Servlets and Java EE components. Java EE services, such as web services, persistence, security, and transactions, enable faster development of smarter communications-enabled applications.
