About OpenSIPS

What is OpenSIPS

OpenSIPS (Open SIP Server) (former OpenSER) is a mature Open Source implementation of a SIP server. OpenSIPS is more than a SIP proxy/router as it includes application-level functionalities. OpenSIPS, as a SIP server, is the core component of any SIP-based VoIP solution. With a very flexible and customizable routing engine, OpenSIPS 'unifies voice, video, IM and presence services in a highly efficient way, thanks to its scalable (modular) design.
What OpenSIPS has to offer, comes in a reliable and high-performance flavour - OpenSIPS is one of the fastest SIP servers, with a throughput that confirms it as a solution up to enterprise or carrier-grade class.

OpenSIPS vision

The OpenSIPS vision consists in a "consolidated diversity" - OpenSIPS is an open source project not only as license, but also as policy regarding the contributions, cooperation and community.
The diversity comes from the large number of people involved in the development of the project and from the complexity and feature richness of OpenSIPS (it incorporates and integrates a large variety of functionalities and features, on top of the SIP routing engine).
To reach a high level of reliability and stability, all this diversity needs to be consolidated. The project brings a consolidate d view on the project management, on the project vision, on the design and code, on the work effort, on the project future.

History

OpenSER project was created by Voice System in 2005 by forking the SER project. In the following years, Voice System was the main contributor and supporter behind the project.

In 2008, the OpenSER project was renamed by Voice System as OpenSIPS project due trademark issues over the old name.

More about OpenSIPS

OpenSIPS project is the continuation of the OpenSER project after its renaming. Inheriting the OpenSER spirit of openness to the community and the will of progress (a continuous work to develop, enhance and extend the code), OpenSIPS continues and extends the OpenSER vision through a strong process of consolidation.
Based on the experience provided by the OpenSER project, such a process of consolidation is critical in order to guarantee the best effort and best results inside the project. A consolidated environment is mandatory for large scale project that aims to deliver professional solutions for industry environment.

OpenSIPS 2.0 Design

Why a new design

The current (pre 2.0) OpenSIPS internal design is based on some concepts older than 7 years. At the time, the requirements were few (simple stateless UDP proxy) and the decisions were made accordingly. But with all the additions, both in SIP and functionality (like TCP/TLS, script manipulation, dialog support, external integration, etc), the existing design is not able to cope with the requirements and use-cases any more.

List of issues that the new design wants to solve].

Preliminary discussions

For almost an year discussions were carried and feedback was received about what issues need to be addressed by the new design.

In other words, the whole community was invited to contribute in generating the set of requirements for drafting the new design for OpenSIPS.

Requirements for the new design

New design description

The first step in making the new design a reality was to compile all the information to generate a proposal / draft for the design OpenSIPS.

Full and detailed description of a the new design.
