Well I'l give it a shot-try this and see if this works-bring up your calling screen by hitting the send button-go into the dial field>hit menu bb key(dotted one)>options>go to call logging>choose to log in for missed call. Don't forget to save your changes! Good luck-hope that works for you on Storm because that's how its done on Curve but I don't think the menus are too much different!!!
