How to Make a VoIP Phone With Google Voice

Ryan Dube 28-05-2018

What would you think about having a VoIP phone that can make calls without needing an active cellular provider? Thanks to Google Voice, this is now a reality.


Google Voice has been around for a long time. But up until now, you could only receive incoming calls from your phone. Outgoing VoIP calling was never an option. Instead, people have been using Google Hangouts for audio chats between mobile devices over Wi-Fi.

Now that Google offers VoIP calling as part of its mobile and web app, customers have a clever way to save money on making phone calls! Here’s how you can make VoIP calls with Google Voice.

Making VoIP Calls With Google Voice

In April 2018, Google announced an open beta program for Android users to test VoIP calling using Google Voice. Signing up for the program is as easy as filling out this simple Google Form and updating your Google Voice app.

When you install Google Voice on your phone, it’ll ask you to link the service to the phone you’ve installed it on. This is so you can make and receive Google Voice calls using the service.


You also have the option to forward incoming Google Voice number calls to your main phone number. You can link the number during setup but then unlink it once the Google Voice app is installed.

Previously, if you installed Google Voice on a phone without cellular service, you couldn’t make outgoing calls. It’s quite significant that you can in the latest update.

On the final setup screen titled Call with Google Voice you’ll see the calling options. These include using Google Voice to make all calls via your phone’s call app, only international calls, or to decide which number to use each time.

  • First, select Linked numbers, and delete the linked number connected to your main phone number.
  • Next, tap Make and receive calls, and select Prefer Wi-Fi and mobile data.
  • Finally, choose Incoming calls, and make sure the mobile phone you’ve installed the Google Voice app on is enabled.

If you set up Google Voice on a regular smartphone with an existing number, you can set up Google Voice to prompt you which phone number to use. In an area without any cell service, but access to Wi-Fi, you can choose to make the call via Google Voice.


If you’re installing the app on an inactive smartphone, you can configure Google Voice to make the call without any prompts.

    Google voice is the best VOIP for people of the USA. We can make all our phone ring at the same time. They also provide to do free local calls inside USA.but international phone calls are not free you have to pay charges. And also for the people who are doing business in the USA ex: E-commerce store operating from the UK but provides service in the USA. These people have to make and receive daily international calls. In my opinion, these people can be benefited with the virtual phone number for the USA CallHippo provides them at very affordable rates a NewYork 212 number will cost only visit::

    Not true I have been using Google voice to make and receive phone calls for years, all you had to do was download hangouts Dialer, make it your default phone app, and boom! Insta VoIP. This info is twothousandlate.

      Same here. I've been using Google Voice for years as well, using the Hangouts Dialer app. For a long time, I had my daughter's phone set up this way without a sim card, but sometime in the last year or two Google made it impossible to do without linking it to a physical phone number. Have they now done away with that requirement again? Or do you still need an active phone number linked to it?
