the rate is 11cents to China, and 7 cents to North America. Direct call. Although they are using IP, but you don't need to enter any other service number before the destination #, which is convenient.

At the same time, I am using IP call service by:

1. DCall, the rate is 10 cents to China. the voice quality is good. But sometimes cannot get through. It's a prepaid service. You can do it online.

2. Phonify. the rate is 8cents plus tax (that is 9.2cents) to China. The voice quality is good. And the charges are accurate. It's a prepaid service. You can do it online.


3. ClearChannel.. the rate is 9cents plus tax. Haven't received the bill yet. But the voice quality is also good.

Hope this helps.
