The ability to make free long-distance telephone calls over the Internet isn't new, but U.S. Robotics puts all the necessary pieces together with its 56K Internet Call Modem package.
Setup is similar to that of other internal modems.
By connecting a regular phone to the modem's phone port, however, you can use it to make free calls instead of a computer microphone connected to the sound card. You'll want to read the manual carefully. Calls are placed using the included Net2Phone software while you're online. Calls are free to any phone in the United States or Canada. International calls elsewhere incur a small fee.
