Preview video calls with Knock Knock

Important: In September 2025, Meet calling will replace legacy calling. Learn about the transition from legacy calls to the new Meet call experience.

When you call someone using Google Meet, the other person gets a live preview video of you while their device rings if they have you as a contact. You won't get their live preview video until they answer.

Important: Knock Knock is available for Google Meet 1:1 and group video calls. Knock Knock isn't available when you join a meeting in the Meet app.
