Hello,

the ACK before does not match the format from the sip trace you sent previously, this one has the r-uri with lr parameters inside it, see the log messages:

Apr 20 11:21:40 kamailio1 /usr/local/sbin/kamailio[6546]: ERROR: <script>: before loose_route M=ACK RURI=sip:172.20.100.74;r2=on;lr=on;ftag=as61fa39de;did=ff7.8c550a93 F=sip:0180290xxxxxx@sipgate.de T=sip:0049511xxxxxxxxx@sipgate.de IP=222.222.222.222 ID=062b0eec058033df3517e99311abe212@sipgate.de

The other one was:

ACK sip:222.222.222.222:5060 SIP/2.0

Also, send the ngrep and the logs together, to match them, only one of them is quite useless. Use ngrep -d any ... in order to catch the traffic on all interfaces.

Cheers,
Daniel
