Not sure, we are a processor and our clients tend to keep traffic info to themselves...
Here's how it works : Chinese surfer makes regular IDD call to Lichtenstein in Europe and pays regular IDD charges to China Telecom. They, in turn, pay a proportion to Lichtenstein who then pay us. We then pay you - every two weeks by wire, check or epassporte. No chargebacks or pending transactions. For China, you get paid $0,50 per password sold. This gives surfers 30 mins access. Great recurring business.
