You could try setting up a telnet seesion using hyperterminal on port 1752 to capture raw data from smdr logs. Hyperterminal is installed as standard on most windows systems up to XP.
Go to start. accessories. then I think communcation.
Open new connection and set port to 1752 and the plug in to 3300 or back of a phone.
I have a doc stating all smdr settings somewhere, I will see if I can find it and post it here, probably tommorrow.
