I found some more headers:

Kannel messed up the UDL (it was 70) and I got an "UDL doesn't match length of user data" from my Siemens m20 gsm modem. So I calculated the right UDL (7bit) which is 80 and now the Siemens m20 throws an error 500 (unknown error), which isn't really helpful ;o) Maybe someone finds the error in my message, I don't know for example what the A7 value is... greetings, Ralph
