I just started using this last week. I have already gotten 10 of my pals and family members to use this. Great quality voice, client design, ease of install and use, Xplatform with PCs and Macs, and best of all... for p2p it is free! Very cheap from a computer to a telephone too (but I have not tried that). A Dutch buddy of mine did and he is a total convert. US to Holland, chatting with his mom $.019 Euros. I am very impressed. How could I have missed this one after trying tons of crapola VoIP. EXCELLENT.
