As to the speed of broadband you'll need, different providers will state different requirements, but a connection of 256kbps download/64kbps upload is generally regarded as the minimum. If you're consistently getting 256/64kbps with your connection (and aren't subject to things like speed throttling during peak hours) then you should be able to run a fairly high quality VoIP connection.
If you're going the netphone route, you'll need a PC and a headset as minimum. If you're going with an ATA, you'll obviously need the ATA, an account with a VoIP service provider and a telephone you can plug in.
Don't forget...
We mentioned it earlier, but remember that using VoIP does take
up your bandwidth. The generally accepted equation is 1MB
download per 10 minutes of conversation -- take into account
roughly how much time you spend on the phone a month and see
whether it will affect any download restrictions that may be on
your broadband service.
Doing other Internet related activities while making a VoIP call can also affect quality, depending on your connection speeds. If you have a fairly slow broadband connection, try not to make downloads while on the phone.
And finally, don't throw away your existing phone. Using a VoIP service requires at least the electricity on and your Internet connection running -- if either of these two are out during an emergency, you won't be able to make calls, whereas you'll still be able to with the normal landline. Some Australian VoIP services, however, provide an automatic forwarding service to your analog phone should the power or the Internet connection ever be down.





There are many more other Australian providers than listed in this story. The site http://www.ozinternetphones.com/ provides a much better reference (disclaimer, I have no connection with this site)
