And cheap too:
"To entice users to stick with Lycos, it's charging less than 1 cent for PC to phone calls made within the continental U.S. The SkypeOut service costs about 2 cents per minute, and Yahoo Messenger with Voice charges between 1 cent and 2 cents per minute."
PLUS free U.S. phone numbers and transmission of voice mail messages to e-mail.
