The easy answer is hitting-home what the actual meaning of a meeting is. If the goal of a meeting is not incredibly obvious and pinned-down [itinerary], of course it's going to feel like some/many [?] meetings and video/voice calls are unnecessary.
Easy mode: don't take/make meetings unless they move the needle in a meaningful way. What 'meaningful' looks like is up to the individual/organization.
Gotta' have 'meaningful' though.
If you don't have the free-reign to sort of dictate your own meeting schedule, and you just keep getting ones that don't feel 'meaningful', it may be time to talk to leadership.
- "Hello, I'm ABC from sales at XYZ, I want to discuss something, let's jump on a call!"
- report spam and move on
For work stuff, have scheduled, regular meetings. For me it's 1h call every other day.
Call me old school but I find that people think more before calling someone than they do before sending an email. I encourage calls and am slowly trying to eliminate messaging apps.
Calendly works great for scheduling timed b2b meetings during specific windows.
Decide on what should be a call and what you can do on Slack.
A one-on-one with a team-member needs to be a call, just like a pitch to a potential new client. As long as you have an agenda for the call, it will be a good investment.
Slack works great for chit-chat and quick questions. Sometimes we decide to "takte this off-line" and out of a meeting, and sometimes I jump into a heated Slack conversation and will suggest a quick huddle on a video-call. It depends!
If you're having lots of ad-hoc video calls, you might need to consider a weekly meeting to address topics that are coming up a lot. It helps people to think things through ahead of time and shortens the time spent on the topic.
