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 Wavecom modem. Could you help me to fill the "???" fields, eventually quoting the specification I should read? Thank you very much for your valuable help. ________________________________________ Claudio Montanari TAI S.r.l.
