I just talked to Angela on the phone and she was thinking of looking into skype, so I will just make it a little easier.

You need skypeout to call from computer to telephone. If you are making international calls you will need to buy credit on a credit card but skypeout is free within North America, so I have heard. All you need is a headset.
