Hi, I am also troubleshooting unexpected no-ack disconnection.
recently I added a modification to catch them before they would take place
in the logs

I found many and they do not seem to be missing anything, the
to/from/call-id and route header are there and when I replay some they work
just fine.
I am now adding more debugging lines in dlg_onroute to isolate the
check/condition that is not updating the dialog on reception of an ACK
I am also having a look at your logs to see if this seems to be the same
problem
