I am trying to understand the WAP Push Service Indication encoding/decoding
vs. the standard specifications.
The chore is really similar to solve a puzzle and now I am close to the
solution, but something is still missing.
Hereby you can find my decoding of SI sent by the Kannel bearer box using a

Could you help me to fill the "???" fields, eventually quoting the

Thank you very much for your valuable help.
