You can do that with Google Voice for free and much lower rates. US/UK/Aus are 1 cent per minute versus 5 on your system, thats your competition.

Google Voice is available everywhere with a little effort. I've used it outside of the US for over 10 years.

Even without GV there are other lower cost options. The actual (wholesale) cost of these services are around what GV charge or less, a 5+ times mark up is pretty rich.
