“On 25th June 2009, Parliament approved an agreement between the Ministry of Communications and Global Voice Group (GVG) S.A., the latter acting as consultant to the National Communications Authority (NCA) in developing a monitoring platform for Ghana's international traffic (…). Thanks to their monitoring system, Government now earns an average of $5 million per month (…). Telecom operators have reported increases in the traffic being routed through their international gateways, due to the steady disconnection of fraudulent lines.”
