Both fraud and origin-based surcharges are on the rise around the globe and pose a threat to the revenues and margins of the telecoms industry.
By pre-validating A-Numbers, carriers avoid having to block traffic due to uncertainty of origin and can also grow customer confidence with their trusted traffic status.
One of the challenges of realtime number validation is in the size of the datasets. By hosting and maintaining multiple large scale databases, XConnect’s services deliver the benefit of query services, avoiding the need to download, integrate, and operate..
Hosted data also supports simple implementation of bespoke services.
