After landing a group call feature in Messenger, Facebook is likely to do the same to the other "child," WhatsApp.
WhatsApp is reportedly testing a group voice call and group video call feature in WhatsApp beta format version 2.18.39.
These experiments are being tested first on WhatsApp Android and will likely be overtaken by iOS.
The group voice call feature will accommodate a maximum of four participants including the first caller, while the group video call only accommodates a maximum of 3 participants including the first caller. The number of participants is still far less than Facebook Messenger.
