Inaki, could you please detail what you mean by:

In my opinion OpenSer does a special treatment for ACK in tm mode, even if
they are for failed transaction (hop-by-hop ACK's) or succesfull INVITE
(end-to-end ACK's).

Maybe I can explain you more if I understand you question....
I meant that, as you have explained, OpenSer keeps the INVITE transaction data
(for discarding retransmissions) and also uses this info to match the
following ACK.
I hope not be wrong, your explanation is clear.
Maybe the only not very correct is the "tm" doc about
"t_check_trans()":
"ACK request - true if the ACK is a local end-to-end ACK for an existent
INVITE transaction."
It could be writen in other way more RFC compliant (reading it seems that the
end-to-end ACK belongs to a transaction when in fact it's a new one, even if
OpenSer uses a previous INVITE transaction data to correlate it). Maybe:
"ACK request - true if the ACK is a local end-to-end ACK for a previous
INVITE."
Best regards.
