I think your English isn't too bad at all ;) I think all you need to do is to send a WAP push SI (session indication) (via SMS as bearerbox) to the user. What happens is this: 1. your backend application makes a request to Kannel's PPG with the corresponding PAP and SI documents as XML (see user's guide) 2. that's received by wapbox literally, wapbox transcodes this to WBXML'ed chunks and sends it as binary SMS to bearerbox. 3. bearerbox sends it as binary SMS to the device, where the UDH data segments contains the WAP push application port number. 4. due to the UDH data segment port header, the device "knows" this is WAP push message and decodes it again to the SI document. 5. the devices presents a question to the user which you can formulate on your own, i.e. "Do you want to make you decision now on the vote?". The "question" is associated with an URL (your WML deck), if the user press "yes", the URL is opened in the corresponding devices browser, if "no", it's discarded. This is actually in detail the initialization phase for getting the user to the vote system. I hope this helps ;) Stipe -- ------------------------------------------------------------------- Kölner Landstrasse 419 40589 Düsseldorf, NRW, Germany tolj.org system architecture Kannel Software Foundation (KSF) http://www.tolj.org/ http://www.kannel.org/ mailto:st_{at}_tolj.org mailto:stolj_{at}_kannel.org -------------------------------------------------------------------
