Stop Fradulent Calls Before They Start (or Ring) - Real-Time Defense with RealNumber DNO

Jun 26, 2025

Stopping fraudulent traffic starts before the phone ever rings. Whether you’re on the network, compliance or fraud teams, blocking suspect traffic is a powerful tool – but only if the data behind it is accurate and reliable. Blocking a legitimate call by mistake can damage trust; failing to block a fraudulent call can result in serious exposure and risk.

Fraudsters often spoof non-originating numbers like inbound-only lines or unassigned blocks to deceive unsuspecting consumers. These calls can slip past detection if your Do Not Originate (DNO) data is out-of-date or incomplete.
