Voice over IP?

[pitupepito2000]

Hi,

I was talking to a friend the other day and he mentioned that there are some programs that freely allow you to use your pc for VoIP. I was doing a search and I came up with the following links:

http://www.asterisk.org/
http://packages.qa.debian.org/o/openh323.html
http://www.wirlab.net/kphone/

My questions are:
What do you guys think about VoIP?
Do you use any VoIP programs?

Thanks,
pitupepito

My home telephone is VoIP from http://www.vonage.com.

Not free, but lots cheaper than my local telco.

I use Ventrilo for communication
