What is the cheepest way to make calls via internet?

Answer 1

Computer to computer using Yahoo Messanger. Free.......

Answer 2

If both parties are on-line, and have at least 70k baud you can use Skype, with just a headset that includes earphones and mike. Some of them make a lot of line noise when you move your head.

If there is a lot of activity on your service you may have gaps in the sound.

Skype from computer to computer is free.

When you want to send or receive calls that begin on a phone system or you make to a phone system you pay for time or for a monthly service.
