Do you have detailed agenda presented to you about the meeting on what it is about and what the it aims to achieve ? I would suggest asking for agenda notes to be included as part of the meeting invite, with the agenda being part of an email or part of visible documentation that is available to the participants. This forces people setting up invites to evaluate if their needs can be accommodated on an email or by a RFC and allows you to respond to the matter when free without waiting for a meeting to happen. You would also then have access to a thread of information, in case new participants are called in and they need to be backfilled.
