Last month, at MWC we heard Jan Koum, CEO of Whatsapp, saying about the addition of voice-calling feature in Whatapp post the 19 billions USD deal with Facebook. There is still long time to see the roll-out of this alleged full-featured app as the CEO has revealed that the the app will be released sometime in Q2 this year for Android and iOS, followed by BlackBerry. But if you can wait till the official launch and want to see how the app will look like after the addition of voice calling support, here is a few screenshots of the app.
An Italian website iPhone Italia has claimed to got their hands-on the latest Whatsapp app with alleged voice-calling support. The website has even posted the few screenshots taken from Whatsapp for iOS which apparently reveal the presence of voice-calling options in the app.
The folks at the website reveal that the app will let you make calls by opening the Whatsapp chat and clicking on the call button. You can do the same in the current version, but it will place a regular call. In the upcoming version of Whatsapp, you will be able to make a VoIP call through Whatsapp via 3G or Wi-Fi. When the call is in progress, you will see a screen something like this.
In addition, you can mute, put the call on speaker or go to the Whatsapp chat screen from the on call screen. you will not be charged for making any call from Whatspp, they report.
