Too bad you can't force people to review prior meeting notes before initiating a new call or meeting.
Simple truth: technology will not fix your culture problems. The most technology can do is serve as a scapegoat for organizational policy, e.g. "the system won't let me do X" instead of "my boss won't let me do X".
If you want to change your culture, then reward positive behavior, fire sources of unapologetic cultural toxicity, and hire people who believe and profess the cultural change you seek.
