Somebody told me to check "VoipStunt" out. It's a free internet phone service. In some countries you can even dial PSTN for free with VoipStunt. (You have to pay with Skype.) Unfortunately, you still have to pay for Indonesia. (Currently, there is a big VoIP fiasco in Indonesia in which directors of Indonesian Telecommunication company were jailed. So, free telephone is not in the horizon real soon now.)
Has anybody make a comparison between these free calls? (Skype, Yahoo! Call, VoipStunt, and the rest of the gang / what else?) I am not keen in installing all these programs in my computer. There are too many programs as it is and I am running out of disk space. Right now, if needed, I use Skype (but it is limitted to people with Skype account only - no PSTN).
