How do I setup my PC so I can make phone calls over the net? What software do I need?
Do I need special hardware?
Here’s a list of providers:

You don’t need special hardware other than a microphone and headphones but you’ll be happiest with a USB handset, such as a Yapphone.
Go to http://www.dialpad.com or http://www.net2phone.com
You don’t need any special hardware. Your PC mic and speakers are enough. You could, if you like, use special handsets as Baraqiyal mentions.
Here’s another provider:
I use BestNetCall. You dial a number, then your phone rings. You pick up and then the number you dialed rings.
PC----->Your phone<---------------------->dialed phone
You only talk on the phone, not through the computer.
