Talk is Cheap focuses on the increasingly popular services from Vonage, which uses VoIP, and Skype--a free service that operates as a peer-to-peer (P2P) network with the ability to turn any PC, Mac, or Pocket PC into a telephone. The book explains your options; explores the background behind, the workings of, and differences between VoIP and P2P networks; and discusses the advantages and drawbacks of both technologies (including service offerings, quality, capabilities, completion rates, and more).
