<p>Kamailio v4.4.x series is no longer maintained for many years. You have to upgrade to use 5.3.x (or at least 5.2.x) if you want the developers of the project to try to help you. There were many bug fixes since 4.4, so what you face might be fixed already.</p>
<p>If happens to still happen on 5.3/5.2, then we will investigate. Open a new issue in such case, because code has changed a lot and we need new backtraces.</p>
