A lot of people know about Skype. A friend talked me into it a while ago. So far, I have been somewhat happy with it. It works well enough, and she swears by it. She used it to call her boyfriend halfway across the world. For me, I just don't care for the layout. There's a new one though.

Go to http://www.icall.com and download their software, and you can make AND receive calls for free. They also offer free customizable voicemail. Not even Skype does all of this.

I am installing this on my husband's computer, and my computer at home. Then we can talk to each other all the time. The kids will be able to call him, and even talk to their grandmas, completely free.
