buzz in
Ring to answer
To buzz in is to grant entry by pressing a button that unlocks a door, typically in an apartment building or secured entrance: I'll buzz you in when you get here.
The phrase also describes activating a buzzer to signal readiness, as contestants do on game shows: She buzzed in before he finished reading the question.
