WhatsApp group video and audio calls are now available for all users after the new features were announced by WhatsApp in Facebook F8 last May. You can avail this feature by updating to the latest version. This feature is currently available only on iOS and Android, however, WABetaInfo on Twitter said, "WhatsApp is enabling group voice and video calls for Windows Phone users too. If you didn't get the feature yet, please wait the next days." How to check if your WhatsApp has this new feature: Step 1: Open WhatsApp Step 2: Select a participant you wish to call. Step 3: Start a video with a single participant. After that, you need to click on the 'Add participant' icon at the top right corner in the video call interface. Once done, the icon will let you see your contact list from which you can select participants to talk to. Step 4: When you add a participant to the video call, that person will be notified of the call along with the remaining participants you have chosen. Step 5: If there is no Add Participant button, then you have to wait for an update. People can be added only by the caller/host who starts the call. A maximum of four people can be added to a group call and the screen will split into four screens with each member featuring in each box. To use this feature, WhatsApp version for group video call is 2.18.189 and the version for group voice call is v2.18.192.
