I've tried "skype" on my laptop (running Fedora Linux) and it is easy
to install and gives a good clear sound. The lag seems to vary depending 
on who you call (average approx 1 second), if you follow their instructions
and open up some UDP ports on your firewall (forward them to whatever
internal machine is running skype) then you get better performance.

The software costs nothing to download and calls to other skype users
cost nothing. Calls to normal phones require you to register with their
"skype out" service but you will save a lot of money if you call long
distance.

Skype is badly behaved with respect to network traffic, it actually
runs a peer-to-peer network in the background and constantly connects
to other skype users. It also probes firewalls (both your own from the
inside and other people's from the outside), presumably all the network
probe results get sent back to "skype central" where they track network
topology and optimise their peer-to-peer routes. This is simultaneously
a good thing (it gives good performance for the user) and a bad thing
(heaps of information about your network is getting sent to a potentially
untrusted third party).

Needless to say, skype is closed source. It certainly would be good to
see the open source world come up with an equivalent, I can suggest
that if you just want to play around with VOIP then download skype
and have a bash about with it... you get an idea of what is possible
to achieve and it is about 100x easier to install and configure
than asterisk (having done both).
