Hello the list,
Just to inform you that the issue was solved.
The error in Kamailio was caused by a wrong signaling from our upstream.

Indeed after the PRACK there is no ? 18x ? packets.
You misinterpreted:
I looked at the code and this log happens when a PRACK is received, but there was no 183 (or other 1xx) response. Can you check the sip traffic and see what packets are sent around?
A PRACK is a PRovisional ACKnowlegde to messages that don't need any responses in plain old SIP. So the PRACK is a correct new message in response to the 18X received (with req rel100).
I'm not seeing these errors in dialog on 4.4.6 setups where upstream demands PRACK.
