Summary
🤩
Rockstar🎓
Top SchoolDaniel-Constantin Mierla is a seasoned SIP and VoIP architect with over 21 years building and leading Kamailio, the high-performance open source SIP server used in large-scale deployments. As co-founder and long-time core developer he has driven Kamailio from a research prototype to an InfoWorld–recognized project that routes billions of minutes and serves millions of users. Based in Berlin, he runs Asipto, delivering consultancy, training and bespoke real-time communications solutions spanning SIP, WebRTC, IMS/VoLTE and load-balancing systems. His work blends low-level C/C++ backend engineering with product and community leadership—evident in focused core contributions to routing, authentication and dialog management in the kamailio/kamailio repo. An active conference speaker, advisor and author of "SIP Routing With Kamailio," he combines protocol-level innovation (early SIMPLE and SIP–XMPP work) with practical operator-grade implementations. Not obvious from titles: he repeatedly led difficult reconciliations in the ecosystem, most notably merging competing SIP codebases to create a unified development framework.
