I think the Korean govt. is systematically working its way through the bases and denying the Vonage service. I know at Osan there have been multiple accounts of people losing their Vonage connection. I personally stood in line behind some Airmen tyring to get their accounts grandfathered, but the service reps couldn't figure out what they were talking about. I realize VOIP takes it's toll, but for a country with one of the fastest internet connections, this is rediculious. Just one more way of sucking the American GI out of some cash when they are "forced" to use the services provided by US govt sanctioned vendors on base. As an alternative, I've found you can use Skype or Yahoo and make calls to the States on the cheap. Maybe not as cheap as Vonage and without all the fanfare, but still cheap in my opinion.
