In July, reports pointed out how developers seemed to be burning the midnight oil with a string of feature updates for WhatsApp including voicemail and Call Back. It was available for Android in the beta mode. Both these features are now officially available on Android and iOS.
For the new features, Android users will have to update to version 2.16.229 and iOS users to 2.16.8. Users can then leave a voice message in case the recipient doesn’t answer the call. For example, they will find three options – Cancel, Call Back and asking to leave a Voice Message.
