VoIP Software


Cost: Free

SkypeSkype is a proprietary peer-to-peer internet telephony (VoIP) network, founded by Niklas Zennström and Janus Friis, the creators of KaZaA. The Skype Group is headquartered in Luxembourg with offices also in London and Tallinn.

The system has a generally favorable reputation for working across different types of network connections (including firewalls and NAT) because voice packets are routed by the combined users of the free desktop software application.

The basic computer-to-computer service allows users to speak, to send instant messages or to send files to one another from their computers via the Internet at no cost. Conferences of up to five users are supported.

SkypeOut is a paid feature of the Skype internet telephony service, which allows Skype users to call virtually any non-computer-based landline or mobile telephone in the world.

SkypeIn allows Skype users to receive calls on their computers dialed by regular phone subscribers to regular phone numbers. Beta released on March 10, 2005, SkypeIn permits users to subscribe to numbers in UK, USA, France, Hong Kong, Denmark, Finland, Norway, Sweden, Estonia and Poland. Cost is €30 for a 12-month subscription, or €10 for a three-month subscription. Users can have multiple SkypeIn phone numbers bound to the same account (a separate subscription is required for each). For example, someone who does business in both San Francisco and Helsinki could create a local telephone number in each city, and callers from those locations would pay cheap or free local rates.

On September 12, 2005 eBay announced its plan to acquire the company for $US 2.6 billion, plus an additional 1.5 billion in rewards if goals are met by 2008. eBay will pay half in cash and half in stock options.

Google Talk

Cost: Free

Google TalkGoogle Talk is a service developed by Google for instant messaging (IM) that also allows for PC to PC audio conversations. Google Talk beta was released on August 24, 2005 and consists of both a service and a client used to connect to the service. Unlike some other instant messaging services, Google Talk uses an open protocol (Jabber) for the IM part and it encourages the use of clients other than their own in connecting to the Google Talk service.

As of the launch date, the Google Talk client is available only for Windows (2000, XP, Server 2003); users of other operating systems are provided with instructions for various popular Jabber clients, such as Psi or Miranda IM for Microsoft Windows and below, iChat or Adium for Mac OS X and Gaim for Linux. However, any program capable of using the Jabber protocol is sufficient, although the voice over IP service only works with the Google client. Google claims they will release a specification for the voice extension in the near future.
