green call button action for textField in S40

Question

Hi ' I have made a j2me application that has a text Field with phone number as constrains and I need the user to press the green call soft key to make a call with the number in the text field It works fine in all Nokia s60 devices but the problem that when deployed the application on Nokia s40 devices nothing is done when pressing that key and no phone calls occur TextField t = new TextField("Phone", "", 10,TextField.PHONENUMBER); Note : I can't used platformRequest("tel:" + Number); as the phone number to be called contain special characters like : # ,* so , is there anyway to make the text field responds to green key pressed in s40 devices using the j2me APIs Or if you have any way to make phone call containing special characters on Nokia S40
