Hello,
I see the in-dialog ACK in the trace, try with dlg_manage() explicitly
used for it.
The warning messages are not when processing the ack, but on dialog
timeout, if you do not get some other errors like 90-120 seconds before,
when the ack was routed, then it was no processing error for it.
Cheers,
Daniel
