The sipXecs Project The sipXecs Project

The sipXecs project was started in 2004 with the objective of building a native Session Initiation Protocol (SIP) based Session Manager.  Today, sipXecs is the largest, most mature and most scalable open source effort in the SIP communications space. The architecture chosen for the sipXecs system represents the original idea of the architects of the SIP protocol to create a SIP session or message router in the network.  The resulting design is highly scalable and offers redundancy through simple DNS based load-balancing between participating SIP proxy nodes.

sipXecs as a system is distributed and consists of a large number of independent components that are centrally managed.  Each component uses SIP to communicate with the SIP session manager at the core and each component has a Web Services XML RPC interface for remote management and configuration.  Each component can be used stand-alone.  A new feature is typically added as a new standalone component, which makes it easy for developers.  

Below you find the different components or sub-projects of sipXecs.  This should represent a good starting point for developers who either would like to contribute to sipXecs or re-use certain components from sipXecs for their own projects.
