EarthCaller: Free U.S. Calling

EarthCaller (http://earthcaller.com), a new PC-to-phone service developed by Jaduka that allows its users to call any landline in the U.S. market for free, has been launched.

EarthCaller is said to run the calls over the Public Switched Telephone Network, with obvious call quality benefits. That's really a teaser for international calling, offered on a prepaid basis.

EarthCaller currently is PC-compatible at the moment.
