<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>
<p>ACK [next_url] SIP/2.0<br /> Via: SIP/2.0/[transport] [local_ip]:[local_port];branch=[branch]<br /> From: sipp <sip:sipp@[field1]>;tag=[pid]SIPpTag00[call_number]<br /> To: sut <sip:[service]@[field1]>[peer_tag_param]<br /> Call-ID: [call_id]<br /> CSeq: 2 ACK<br /> [routes]<br /> Contact: sip:[service]@[local_ip]:[local_port]<br /> Max-Forwards: 70<br /> Subject: Performance Test<br /> Content-Length: 0</p>
