SailFin is an open source SIP application for the GlassFish Java application server.
From: SailFin Website
Project SailFin is based on robust and scalable SIP servlets technology on top of a deployment-quality, Java EE-based GlassFish. We are JSR 289 compliant, and provide high- availability and clustering features while 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.
We are very excited about this project. Come and join us in building a vibrant SailFin community!
