Google had been a receiver of laud since its inception in the world of Technology. And with the latest breakthrough, it is bound to be in everyone’s good books.

At a recent Google Apps multimedia training presentation, it showed a Google Talk with “Show dialpad” in the user interface on slide 9. Presently, Google Talk enables users to only dial other Google Talk users. The Gizmo Project doesn’t support PSTN dialing from Google Talk, however, some third party add-ons allows PSTN dialing from Google Talk such as GTalk2VoIP.

Take a look at this latest screenshot from the official google page. Is SIP-to-PSTN calling from Google Talk be far behind? And the very next question which comes in line is whether PSTN calling free of charges? Since, over the years we have been seeing most of their services granted free, so it wouldn’t come as a surprise if they do it really free of cost.
