<p>I pushed the commit <a class="commit-link" data-hovercard-type="commit" data-hovercard-url="https://github.com/kamailio/kamailio/commit/785326cdfbee849a8436e7c07003ff0539d259cd/hovercard" href="https://github.com/kamailio/kamailio/commit/785326cdfbee849a8436e7c07003ff0539d259cd"><tt>785326c</tt></a> to allow 183 without contact. An 183 creates an early session, can be followed by PRACK, which needs the contact, I am not sure now if it is mandatory, but I have seen 183 without contact, so it should be fine to accept it without contact. It will be backported till the next point release.</p>
