Hei there
i send with the .net interface a message with usercontext. like this:
IntelliSMS objIntelliSMS = new IntelliSMS();
objIntelliSMS.Username = "username";
objIntelliSMS.Password = "password";
           
String MessageId = objIntelliSMS.SendMsgWithUserContext
    (txtMobileNr.Text, txtMsg.Text, "swissphil", txtUserContext.Text);
but when I reply (with a samsung mobile) and the message gets forwarded i havent got a usercontext in it:
        string usercontext = "usercontext";
        if (Request.Form["usercontext"] != null)
            usercontext = Request.Form["usercontext"];
the usercontext is always null.. 
any clues?
