Need help with voice over internet...

I'd like to find software that allows me to make a call to a telephone from my computer. I know there are many out there, but are there any for free? Several years ago, I would make international calls for free over my computer, but that was with a windows machine. Now, I can only find services that charge a fee. Are those free calls days over? Anybody know of a mac program that will allow me to make computer-to-phone calls for no charge?

Thanks for reading...

yes there are free ones... skype

I'm guessing the poster is looking for a service that allows computer-to-telephone calls, and not computer-to computer calls? Such as dialpad.com used to offer for free, and not a service like Skype (or iChat AV.)

I'm not sure if there are any free services left...anyone?

I would like to know thi stoo......
