Since the service added voice calling feature, there were reports that the messaging service will add call back and voicemail feature too. With record voice message option, user can simply send a recorded voice message like voicemail. The updated WhatsApp app is available to Android Beta user group and also available in the form of a signed APK from APK Mirror. Now finally WhatsApp is rolling out the feature to its Android Beta program users.
