I would ask your upstream SMSC hoster to send you a copy of the ACK they claim
came from kannel - preferably as a packet capture, which you can then compare
with your own.
After all, you say "there is no ACK" and you cannot investigate something that
isn't there. They are saying "there is an ACK", so that is where to start
investigating.
