Please, read carefully userguide and especially section about delivery
report. After that describe your configuration and the problem you have.
Then you can expect that the someone could answer your question.
Anyway, from my experience best way to handle SMS with Kannel is to
write small program in scripting languages of your preference and
knowledge. I wrote some simple skripts in perl ten years ago that worked
(and I think still works) for SMS parking payment in one country.
