Types of Free Calls With Google Voice
Google Voice can be used to make free PC to phone calls and free PC to PC calls.

The easiest and most common way to use Google Voice, however, is to allow the service to connect your phone to the destination number for free. I suppose you could call this a free “phone to phone” call.

Sign Up for Google Voice
You can sign up for Google Voice for free from your Google account, which uses the same information you use to access other Google services like Gmail and YouTube.

If you don’t already have a Google account, sign up for one using this link.

Read and accept any terms or policies, and then go into your Google Voice Settings. At the top of the page, inside the Phone numbers tab, click CHOOSE.

You can then search for a number based on a city’s area code. Type in Atlanta, GA, for instance, and you’ll be given all the numbers you can choose that have Atlanta area codes. Choose SELECT on the number you want.
Then, go through the step-by-step process of linking your existing phone to your Google account so that you can use your Google Voice number with your tablet or phone.

How to Use Google Voice
To use Google Voice to make free phone calls:

Log in to Google Voice and click the Calls menu button off to the left.

Choose Make a call and then enter a name or number in the Call section.

Making a Call in Google Voice.
To use Google Voice to make free PC to phone calls, install the free Google Voice and Video Chat Plugin, also called the Hangout Plugin. Once installed, you can make free calls from the Chat or Hangouts area in Gmail to real phones using just your PC microphone and speakers.

PC to PC calls, usually called voice chat or video chat, can be made using Google Hangouts.

You can also use Google Voice from a mobile application. Official Google apps are available for Android, BlackBerry, and iPhone, iPad, and iPod touch users.

Google Voice Limitations
Free calls made with Google Voice are limited to three hours in length, at which point you’ll be disconnected. However, you’re free to call the same number over again as many times as you like, so this is more of an occasional annoyance than a true restriction.

Also important to know is that calls with Google Voice are free only if you call numbers based in the United States or Canada. Calls to numbers outside the US and Canada will incur a small per-minute fee.

PC to PC calls using Google Hangouts are not restricted.

My Thoughts on Google Voice
I love Google Voice. I’ve used it personally since it was GrandCentral, before Google bought the company. The free phone calls are clear and it’s a very easy service to use.

The mobile app I’ve used on an iPhone is user friendly and works great each time I need it.
