If you’ve still haven’t got the WhatApp voice feature activated , then here’s what you need to do. Firstly, download version 2.11.528 from the Play Store or version 2.11.531 from the WhatsApp website. Once you have the latest version, voice-calling ability can be activated by receiving a call from someone whose voice-calling is already activated.
The WhatsApp voice calling feature is available only for Android, and is expected to make its way to iOS users soon. At the Facebook F8 conference held recently, WhatsApp cofounder Brian Acton said that the messaging service is preparing to bring the voice calling feature to iOS users in the coming weeks. It is known that some tech enthusiasts have already found out ways to activate voice calling on iPhones. However, that requires jail breaking the iPhone.
Interestingly, WhatsApp calling seems to be now open to all in India, just when reports about Trai seeking views to prepare regulatory framework for Internet-based calling and messaging applications or over-the-top (OTT) players have started surfacing online.
