Are your customers complaining about inaccurate billing?

Sometimes, calls are connected or charged inaccurately without ever reaching the receiving party. These fraudulent billings often go unnoticed, because the billed call duration per user lies just within the fraction of a second; however it could also have a greater impact on customer satisfaction.

Interconnect fraud also contributes to early charging and false answers of connecting calls. This may be caused by VoIP traffic via illegal gateways or faulty confi gured carrier equipment. Also, prepaid SIMs used in SIM Boxes often cause false answers in the instance of mailbox announcements which are being charged as a call connection, all resulting in wasted SIM credit.

The outcome is always the same: Customer complaints and dissatisfaction with the service.
