About

OpenJSIP is a GNU GPL licensed bundle of free distributed SIP services run by Java VM.
Distributed means that these services can be deployed on different hosts communicating with each other with the help of Remote Method Invocation (RMI). Distributed architecture allows creation of redundant and load-balanced systems.

At the current stage of development (v0.0.4) the project includes:

• SIP Proxy
• Statefull operation
• Stateless operation

• SIP Registrar
• Standalone (can listen to requests itself)
• ViaProxy (proxy listens to requests and deliver registrations to registrar)

• SIP Location Service
• No database integration. Keeps data in memory (for now)

OpenJSIP is based on SIP stack provided by JAIN-SIP project. Thanks to all the authors for this incredible work.

Here are some silly screenshots.

Architecture

• OpenJSIP services running on one host

• OpenJSIP services running on separate hosts (distributed model)
