HI,
If you enter code 333 while the phone is idle this should bring up a menu that will list type of call history.
You can also assign yourself a button (As long as it is a user programmable key which can be altered in the System and diagnostics software, mihgt need to contact your system provider for this), Enter 397 - press the key you would like it assigned to, then enter 333.
You should now have a button which will provide you with Call history features.
