One of the most well known netphones is Skype, which boasts more than 146 million downloads so far. Such is its popularity that several phone manufacturers are releasing phones that can be used to directly interact with Skype, freeing you from your computer (although it still needs to be on). New products include DUALphone's 2-in-1 Skype Internet phone and Doro's USB telephone 212 IPC for Skype. Skype also has SkypeOut, a paid service which allows you to call landlines and mobiles, and SkypeIn, which gives your Skype account a physical phone number that anyone can call (although this service isn't available for Australian customers yet). You can download Skype here.
Other popular netphones include BuddyTalk and Glophone, both of which are free to use between other subscribers but do offer advanced services for a fee.
But it's not only international companies getting in on the act. Melbourne-based Freshtel has developed Firefly, a free netphone that, like Skype, allows you to talk for free to other Firefly users (and charges for calls to landlines and mobiles).
Another option is to use your favourite instant messenger application, many of which now have features which allow you to make VoIP calls. The latest versions of MSN Messenger and Yahoo Messenger, for example, now incorporate voice chat capabilities.
