I have played around with kannel for a while and have initiated a SMPP connection to my provider. Works great! My Provider needs the optional parameter its_session_info set for MT SMS (MO SMS works fine). I've tried to understand the preproc stuff (Is there any documentation about that?), I think I know that I have to "hardcode" that in function msg_to_pdu (for test purposes), but how?
there is no exclusive documentation on the preproc magic, unfortunatly ;(. It's a bit tricky to understand, even while very powerfull in its backend usage.
Ok, this preprocessor magic pretty well described. See http://liw.iki.fi/liw/texts/cpp-trick.html
Simply think of real macro'ing of the things defined in the .def files and how they are #define'ed within the sources. Sorry, it's hard to explain in two sentences.
Kannel does currently not use optional (v3.4) parameters. They are very specific to SMPP and as be try to abstract the frontend (smsbox for MT direction) to all supported protocolls, there is no way to inject data to specific optional parameters of the SMPP module.
If the data you have to store in the optional field is static, you can hardcode it within the smpp packing (msg_to_pdu) function. Even while I'm not sure if the encoding for the optional parameters is yet done?!
