windows user will catch new WhatsApp voice calling feature.
Till now, it was available for android only and now iOS and windows phone will get new WhatsApp update having voice calling feature.
WhatsApp on android is now free from sending invitations in order to enable voice calling.windows phone will get all update in a single phase.
There are many other problems exist on WhatsApp for windows phone like mp3 sharing. So probably a solution to this problem will hit this time.
On 2G network, there is some lagging due to weak signals so I suggest you to use 3G cellular network while calling.
WhatsApp voice calling feature for windows phone is in beta phase yet and any user can test it but there is a lot of probability of bugs yet.
