DNO (Do Not Originate) is a tool that is effective for combatting fraudulent activity and spoofed phone phone calls by preventing the traffic from existing on your network.
DNO is a flag that can be selected on numbers that do not originate calls, examples of that are certain call center numbers that do not make outbound calls.
