<p>Wim,</p>
<p>Looks like your ACK is missing the Route header, since ACK is a new transaction kamailio needs to route it based on a preloaded route. When you receive the 200OK in sipp you should save the record route set and use it in the ACK with the "[routes]" statement.</p>
<p>Take a look at the SIPP docs and search for rrs="true". If you take a packet capture on the loopback interface of the kamailio server you will probably see that kamailio keeps looping the ACK until the Max-Forwards is exhausted.</p>
<p> </p>
<p>Example:</p>
<p><recv response="200" rtd="true" rrs="true"><br> </recv></p>
<p><send><br> <![CDATA[</p>
