Voice chat over the internet

Hey everyone. I was wondering who uses voice-chat over the internet? I've used Skype yesterday and it worked pretty nice. There is only one problem and that's the CPU useages that sometimes gives my voice a weird digital sound. I've also been looking on the Internet and there seem to be more programs. Yahoo is also been developing a voice-chat program http://messenger.yahoo.com/ and there is another program called "Jajah" http://www.jajah.com/en/features_ahead.asp that is also compatible with Skype. By the way...you can download Skype from http://www.skype.com/

It's really cool to be able to talk on the internet for free with other persons without an extreme delay. Nice for learning languages ;)
Have fun voice-chatting!

By the way...my name is Meazrael on Skype ;)
I currently still have to install the Yahoo and the Jajah messenger. Let's see which one is the best.

Yes. That was cool. And free of charge. And cool.
