Ok, maybe I should call them. But, as I said, if all their product does is measure QoS and then give you pretty graphs to eyeball, it isn't much use. I need something that can measure jitter, latency etc in real time and then stick the results somewhere, such as in MySQL. I can then choose ITSP's based not just on route cost, but on a combination of route cost and historical QoS data.
