Abstract
A telecommunications system, service control point and method are described that can pre-screen a telephone call to help prevent telephone toll fraud. More specifically, the telecommunications system includes a service control point capable of receiving information about a telephone call originated by a calling party, and further capable of determining whether the telephone call has a fraudulent attribute. If the telephone call has a fraudulent attribute, then the calling party is informed that there is a possibility of telephone toll fraud occurring if the telephone call is connected to a called party. And, if the telephone call does not have a fraudulent attribute, then the telephone call is automatically connected to the called party.
