Announcing the news, Google India in a Google+ post said, "Starting today, the Hangouts app on your phone will help you stay connected with your family and friends around the world in more ways than ever. Now you can make voice calls to phone numbers outside of India on Android, iOS, and the Web from Hangouts in Gmail."
The search engine giant revealed that people in India can now call international numbers in the US and Canada for free, while for other countries the rates are "really low."
Google Hangouts users in India using Android devices will have to install the Hangouts Dialer app from Google Play to turn on voice calls. Meanwhile, users on iOS and the Web will get the option to make voice calls automatically. The company said, "On Android, just install Hangouts Dialer to turn on voice calls. On iOS and the web, voice calls will be available the next time you open the app."
"You can make and receive calls as well as get your text messages and voicemails for your Google Voice number through Hangouts. To use Google Voice with your Hangouts account, you need to have a U.S. Google Voice account and number," adds Google.
The company also announced that that the first minute of calls to 24 countries from India will be free and users will be charged for each minute after. The first minute will be free for calls to these 24 following countries - Australia, Belgium, Brazil, Canada, China, Dominican Republic, France, Germany, Indonesia, Ireland, Italy, Japan, Mexico, Netherlands, Norway, Peru, Poland, Russia, South Korea, Spain, Sweden, Switzerland, United Kingdom, and United States.
Google's support page notes, "Calls where the first minute are free will say, "First minute free" on the call screen. If you don't see this message, you'll be charged for the first minute."
The company back in September rolled out the voice-calling feature from Hangouts app.
