In what's rapidly becoming a holiday tradition, Google announced Wednesday that it's extended free calling in Gmail for another year.
First added as a feature to Gmail in 2010, the Call Phone option lets Gmail users place calls to landlines and mobile phones from within the web-based email client.
If Wednesday's announcement sounds familiar, that's because it echoes similar extensions offered last year and in 2010. At the time calling features were added to Gmail two years ago, Google had said that it would start charging for domestic calls at some point. But that point appears to be pushed farther into the future once more.
