BanglaHunt Desk: No worries if the network is gone in the phone call Automatically make calls to your Airtel or Geo connection from a WiFi network. This is because VO-WiFi allows the phone to automatically switch between cellular connection and WiFi when making calls.

Vo-Wi-Fi or Voice-over Wi-Fi can be used in regions where there is rarely a network. This is because Vio-WiFi uses IEEE 802.11 – it's a fancy thing for WiFi to call. So, if your phone is connected to a good Wi-Fi network, say for example in your home, when you make a call using a phone dialer or in other words a regular phone app, the call will go through the WiFi network. This is similar to how a call is made using WhatsApp but there are some differences, which is that the call will automatically move to the cellular network if the WiFi network fails. If the wifi network fails in case of WhatsApp call, the call will fail. There is no fallback option.

According to an ET report, Airtel's WiFi has exceeded one million users a month with the launch.

The funny thing is if VoIP gets enough attention, then very, very soon, applications like WhatsApp, Viber and Hangouts can compete that can be used to make VoIP calls.
