A while ago I took a trip to Korea, and being highly dependent on my phone I spent a long period of time testing numerous applications on my ppc for use with the Vonage softphone service including sjphone. In short, Nothing worked. I tried every configuration humanly possible. There is a protocol that Vonage uses that limits it's use to one program only and only usable on a PC. So after many wasted hours of trying to find a good solution I was only able to use the PC as a softphone using Vonage.
Maybe something has changed since then, but I doubt it.
