[CUBE] Audio/Voice conferencing on the web

[Bryce McKay]

You could also try the free cross-platform software IP Phone X-Lite from
http://www.xten.com/
You will need to create a free user account with
http://www.freeworldialup.com/    as well.  They help route the "phone
call".

Computer to Computer calls are free and you can sign up with other providers
if you want really cheap Computer to Phone calls.

Unfortunately Audio only though...
