VOIP provider for International Calls

[Taz]

I currently use Skype to make VOIP international calls when i'm travelling. I was wondering if there are better alternatives as I don't really rate Skype very highly due to poor audio quality and high call charges. I guess the computer-to-computer audio quality is okay with Skype but they just re-route computer-to-landline calls via a third party, it appears, and the delay and quality is very poor.

I am currently using VOIP Stunt. They are pretty good. A lot of free international phone calls as well. The only thing I dont like about them is that they give you like 100+ or so days to use your credit.
