Now you can call anyone with WhatsApp, even if they don’t have WhatsApp

WhatsApp's new guest calling feature allows you to invite anyone to a call, without needing them to make an account first. They won't need the app, either, since Meta also added support for calls on the web version of WhatsApp earlier this year. You can invite guests just by sending them the call link, and guests still have access to call features like hand raising, screen sharing, and emoji reactions, complete with end-to-end encryption.
