Abstract: Techniques are disclosed to determine one or more specific data points that may be found in or added to call metadata that will assist and/or enhance confidence score algorithms. A call request for an inbound VoIP telephony call may be received by a telephony server in a servicing telecommunications carrier network. The call request may be intended for a called party serviced by the servicing telecommunications carrier network. The servicing telecommunications carrier network telephony server may obtain a plurality of data points associated with the call request wherein at least one of the data points is an interconnect carrier, the interconnect carrier data point identifying which carrier handed the call to the servicing carrier. The servicing telecommunications carrier network telephony server may then send the plurality of data points to a confidence score generating process comprising an algorithm configured to determine a confidence score using the data points.
