It is possible to use VOIP with a computer that has a microphone. You can also use specialized VOIP phones or adapters which allow your regular phones to use VOIP. The exact details depend on the different providers.
You can also use VoIP using a mobile/cell phone.
There are tons of VOIP programs out there. The one I currently use is Skype. Skype is one of the best VOIP programs ever made. I highly recommend it if you want to use a VOIP program.
