The ability to make audio calls in Duo is rolling out worldwide

Back in March, Google unveiled audio-calling in Duo but limited it to users in Brazil. At the time of the announcement it promised to bring the feature to the rest of the world “in the coming days,” but the global rollout took a little longer than expected. Nearly three weeks later, it’s finally arrived.

To make an audio call, simply switch the toggle at the top of the screen from video to audio.
