An app that is not using SIP or VoIP

Our idea was to transform a voip call into something that is proven. So instead of doing a voip call we make a normal mobile call but not to the destination number but to a fixed line number attached to one of our servers. Some might argue that data is cheaper but it really depends which mobile contract you have. National flatrates or plans with a big amount of fixed line minutes are available for any budget.
Technically we combined the idea of a normal mobile call with a very little data packet sent before the call starts. The single data packet has all the information our server needs to forward the mobile call to the voip provider. We can now present our business number and as a positive side affect we benefit from low international call rates.
We developed the idea and finally filed for a patent. The information is now public and can be
