This feature to will be similar to the "recall" functionality said to be coming to WhatsApp soon.
WhatsApp added the option to make voice calls a year ago but the new feature would allow users to add multiple people to the same call.
An image recently released by WhatsApp suggests the next update could also come with group video calling, the site claims. "And if more than one person shares their Live Location in the group, all locations will be visible on the same map".
The WhatsApp group call feature never lets the group creator to be deleted from the group. The Facebook-owned messaging app has been adding a lot of feature for its over 1 billion users. The references for the same were spotted in the iOS beta version 2.17.70.
WABetaInfo recently tweeted about the tools, claiming that version 2.17.70 of the iOS app has very hidden references to group voice calls.
Apps like Snapchat, WhatsApp, Facebook and Instagram have been increasingly "borrowing" features off one another. As mentioned, the new feature will roll out with the latest the IOS app.
In a written statement, a spokesman for WhatsApp said: 'Today, we're rolling out a new feature that allows you to share your location in real-time with family or friends. In the code, it was discovered that, calling someone who is already on another call, sends a request to the server in order to check whether the user is busy in another group call.
According to technology website Teknepolis, one major update is that when you change your phone number in WhatsApp, your contacts would receive notification of the update.
The administrators on WhatsApp groups will also be able to choose if other participants can modify the subject of the group, its icon, and its description.
It is expected that the new feature will work just like the Skype group calling. Since this update comes in form of APK, WhatsApp users are required to manually downloading and install it themselves.
