VoIP on Skype

Skype is a reputable service that, when used a specific way, will be completely free to you. The software is easy to download, and talking to any other Skype user is free. Rest assured that there are plenty of Skype users out there, too, as it is currently the most popular VoIP service. If someone you call frequently doesn't use Skype, you can merely send him/her the link to easily download the software. Long distance phone calls to your mom in another state, for instance, will at once be pain-free for both you and her. A professional site and customer service, in addition to clear sound, makes this a legitimate winner for most.

The free feature is only available when calling from one computer to another. If you are interested in dialing regular landlines from your computer, Skype offers unlimited calls to all of North America for $30 a year. Not steep by any means, but still not free. Also, there is controversy about their use of supernodes, which could put your computer at risk of contracting a virus.
