Go to www.mediaringtalk.com and download the internet call services. I just realised how cool internet calls, PC to PC, is. Last night, I was on the phone with Amanda for 1.5 hours, for free. Voice quality pretty clear, most of the time. Once in a while, it gets choppy for a short time.
Why do I think it's a good service? For one, because it's free, you don't have to keep talking. Sometimes both of us weren't talking at all, but we didn't want to hang up and it wouldn't cost us anyway. Secondly, you can do conference calls for up to 6 people in the conversation. That means, if you're too busy with all your friends to meet up for project, you can have a meeting at 10pm!
In fact, I did have a conference call on my handphone with 4 other people and man, it was 40 minutes! Thank God I have 250 mins of talktime.
How did I get to know about Mediaring? Well the CEO came down to SMU to give us a talk, in lieu of a lesson for the module called Technology and World Change. :D
