Opensips is an open-source SIP (Session Initiation Protocol) server that facilitates the management and routing of voice, video, and messaging communications over IP networks. It enables scalable and flexible VoIP solutions by handling tasks such as call routing, load balancing, authentication, and NAT traversal.
About Opensips
Opensips was created in 2008 as a fork of the SER (SIP Express Router) project. It emerged to address the need for a more flexible and scalable SIP server capable of handling extensive VoIP deployments. The project aimed to enhance features and performance, providing a robust platform for managing IP-based communications.
Strengths of Opensips include high scalability, flexibility, and strong performance in handling large volumes of SIP traffic. Weaknesses involve a steep learning curve and complex configuration. Competitors include Kamailio, FreeSWITCH, and Asterisk.
