Automatic profile doesn't work

[Guest raven2000]

According to the description it is supposed to "switch between Vibrate and Normal profile when the calendar indicates that the current time is busy." The problem is this doesn't work. I have tried adding two test calendar entries with Busy status but the phone doesn't change the profile and when I tried ringing myself the phone rang even though it should have been on Vibrate.

Has anyone had this problem before?

Thanks.
