The slides for the Kamailio World 2024 presentation about automating your test calls. It dives into why automated sip and webrtc testing is crucial, how to integrate it into your CI/CD pipeline and how to extend testing of single calls into load testing and testing of other protocols. The presentation also provides details how kamailio and rtpengine are used to implement an SBC and how the combo is utilized to generate test calls at scale.
