While Google has shut down Allo and Google+, the company is still putting effort into its video calling app, Google Duo.
Google Indonesia announced the feature in preparation for Ramadan, then Justin Uberti, lead of the Duo division confirmed its release in other regions.
Reportedly the function is easy to use and allows users to select four contacts to call simultaneously or create a group.
Back in February Google launched Duo for web browsers.
