Google has extended their offer of free domestic calls within the US and Canada through 2012, a kind holiday gesture to Google Voice users in Canada and the States. The catch? You will have to place the calls via Google Voice and G-Mail, excluding Android users wishing to make calls from their mobile device.
Google’s offering provides a good service, and Google has the benefits of having a lot of users that already have a Google account. Now, it is a matter of giving them a taste of something that they will come back to, and there’s nothing like a holiday giveaway to do it. To place a call, you just need a Google account and the voice and video chat application.
