I've been using Fring for IM, but want to get it working with VoIP via a SIP account. What service do you all use for this? All I want to do is be able to make calls from the USA to the USA for free. I don't care about international calling. I don't want to use SkypeOut because it's not free from my understanding. What's the best option? I've heard of voipstunt and voipbuster and voipcheap and the others that Fring has pre-loaded, but they all have restrictions on free minutes it looks like. There has to be a good free solution out there. Any feedback would be VERY much appreciated.
