The Cost of a Phone Call Drops to Near Zero

The title of this post is true, under certain circumstances. Last week’s e-mail brought word from Michael Robertson of Backdoor Dialing – Free Calling to Millions of U.S. Phones. By using Gizmo, the freely available, no-spyware computer-based telephony application, it is now possible to call about 10% of the mobile and land lines in the country for no per-minute charge. This looks like another chink in the armor of the traditional voice telecom way of doing business, on their way to being disrupted out of existence (as they are known today).
