free phone call

[makintosh]

Hello,

How can I make a free phone call with iMac? Family and friends use windows messenger, I tried to download it, but it didn't work.
Is there any program out there that I can use to make a phone call from Mac to PC?

thank you,,

If your friends have AIM accounts, you can use iChat and connect with them.
