OpenSIPS

OpenSIPS is an open-source SIP server implementation designed for professional communication platforms. It operates as a server-side application that manages Session Initiation Protocol traffic to facilitate voice and video communication across networks. The software is licensed under the GPL and is maintained by a team of developers focused on reducing development latency for new feature releases to ensure a shorter path from development to production.

Users deploy OpenSIPS to handle SIP signaling and routing in environments that require high performance and security. It is used as a core component in the infrastructure of communication services, providing the necessary logic to direct traffic between endpoints and other network elements. The software is installed on servers and configured to manage the flow of communication data, acting as a proxy or registrar depending on the specific needs of the network architecture.

Key features

• SIP server implementation for communication platforms
• Modular architecture with a wide range of available modules
• Support for high performance traffic handling
• Security focused design for professional environments
• Open project management for external contributions
• GPL licensed source code
• Dedicated mailing lists for usage and development support
• Comprehensive module documentation within source directories

The software is built on a modular system, allowing administrators to add or remove specific functionalities by configuring different modules. This architecture makes it suitable for developers and network engineers who need to customize the behavior of their SIP proxy or registrar to meet specific business requirements. The project emphasizes openness in its management, encouraging external contributions to the codebase to accelerate the addition of new features.

Technical support and community interaction are managed through several public mailing lists. These lists are divided by purpose, covering general usage, core development, bug reports, and business consultancy. This structure allows contributors to collaborate on the codebase while providing a path for users to receive technical guidance on installation and configuration.

OpenSIPS serves as a foundational tool for organizations building scalable API infrastructure and customer communication platforms.
