Hey Ahmad I understand where you are coming from with this hidden variable idea.
As far as I know, the only way you can tell that you are receiving a reply, is from the mobile number itself. (%s) I have heard that each SMS message has a unique id, but I don't think Kannel currently has access to it (??) I have thought about ( not implemented ) this sort of reply type system before. I can see a way, albeit has problems. If you where to keep track of the 'to' mobile number that your user send to, along with a record of their id ( say for a web reply ) If you then receive an SMS within a certain amount of time, from this number you can safely say its a reply and send it along to the user, via the id record ( say as a email ). This is not an ideal solution as a few caveats exist with users sending SMS to the same person within that time frame. But this would work with a small user group. Forget about this if you have large amounts of SMS traffic. Also your sms services handlers might be effected as a reply could contain that keyword your bearer is expecting and reply with a say a weather report or the score for the footy. ;-) Has anyone got this sort of reply via sms center working ?
