And it now seems the hugely popular messaging app has started rolling out the feature to a select number
of users, according to Daily mail UK report
A screenshot, posted to Reddit at the weekend, reveals how
the Calls tool looks on a Nexus 5 device running Android Lollipop.
In the image, a new tab has been
added that shows 'Calls', in addition to the existing 'Chats' and 'Contacts' options.
Users can then
open the Calls tab, select a contact and make a voice call using an internet connection.
This is similar
to how Skype connects web-based calls, a service known as 'voice over internet protocol' or VoIP.
In December,
Dutch site Android World uncovered clues about Whatsapp's voice calling feature while studying the app's test code.
Expert Sander Tuit then extracted layout files, images and text from the raw code to create a series of mock-up
screenshots.
The latest grab was posted to Reddit by user pradnesh07, although it has since been removed because
it contained personal details.
