Do-Not-Originate DNO blocking

TransNexus provides Do-Not-Originate detection, reporting, and blocking services. These services are available with our ClearIP and NexOSS software platforms.

Spoofed calling numbers

Fraudsters often spoof the calling number on their calls to trick consumers into answering their calls. The spoofed number enables them to impersonate a large well-known government organization, such as the IRS, or a private entity, such as an electric utility company. When a consumer sees an incoming call from that number, they might be more inclined to answer the call.

Do Not Originate

The entities that hold these calling numbers know that their numbers are being spoofed from callbacks they receive from consumers. Often, the calling numbers are inbound only—the organization never makes outbound calls from those numbers.

These organizations can protect their reputation, avoid time spent with upset customers, and prevent their customers from becoming victims of fraud, by registering these inbound-only telephone numbers with a Do-Not-Originate (DNO) call list.

Voice service providers can use these lists to identify, report on, and block these illegal calls.

DNO regulatory mandate

In the U.S., the FCC has issued a rule that all voice service providers in the call path must use a reasonable DNO list to block calls. This includes providers that originate, transit, and terminate calls.

DNO blocking benefits

Voice service providers gain many benefits from DNO blocking:

Easy compliance with the DNO mandate
Better robocall mitigation to prevent the origination of calls with DNO calling numbers
Improved network efficiency by removing fraudulent calls from your network
Enhanced robocall prevention so your subscribers are protected from fraudulent calls.

Fast, affordable compliance
