Use revenue share NGN’s (Non Geographic Numbers) published to your customers to allow them to make calls to limited destinations based on the revenue share.
Easy for customers to use, simply advertise your revenue share numbers to the general public, all they do is call the appropriate revenue share number, they get secondary dial-tone, then they dial the number they want to call.
Your revenue share number provider pays you for the call.
If the incorrect access number is called, the dial-plan re-routes them to an IVR where the correct access number for their destination can be read out.
Cost to implement: €300 Euro
Requirements: A2Billing and a range of revenue share numbers.
