No real video call needs you to install a 'fix': verify invites out of band and hang up on audio-error prompts
- Confirm unexpected meeting invites through a different channel than the one they arrived on, even from people you know.
- Only join meetings in the vendor's installed app or its real domain; never install software or paste commands offered mid-call to fix audio or video.
- Maintainers: use hardware-key MFA on repo accounts and keep publishing credentials off the machine you take calls on.
