This product has charges associated with it for seller support. Kamailio is an open-source SIP server used for building scalable VoIP, messaging, and real-time communication systems.
Overview
Kamailio is a powerful and highly scalable open-source SIP server designed for building real-time communication infrastructures such as VoIP platforms, SIP trunking systems, presence services, and messaging networks. It acts as a SIP proxy, registrar, and load balancer, capable of handling thousands to millions of concurrent users.
It is widely used in telecom and enterprise environments to build Session Border Controllers (SBC), IMS cores, and carrier-grade communication systems. Kamailio is highly modular and supports integration with databases like MySQL, PostgreSQL, Redis, and external authentication systems.
Administrators configure Kamailio using a flexible routing script rather than a GUI, allowing fine-grained control over SIP traffic routing, security policies, NAT traversal, and load balancing strategies. It is often deployed alongside media servers such as Asterisk or FreeSWITCH for full VoIP solutions.
Highlights
- Highly scalable SIP server capable of handling carrier-grade traffic
- Fully modular architecture with database, TLS, and WebSocket support
