SIPNOC 2026 brought together the people working at the heart of trusted communications — from network operators and service providers, to technology companies, regulators, and industry experts — to tackle some of the most important challenges facing voice and messaging today.

Held September 15-17 in Herndon, Virginia, this year’s conference continued its focus on call authentication, STIR/SHAKEN, robocall mitigation, fraud, All-IP interconnection, and the technologies needed to create greater trust across communications networks.  Discussions throughout the event touched on call analytics, vetting, ALIII, traceback, delegated certificates, cross boarder authentication, and the challenges of combating evolving telecom fraud.

For netnumber, the conversations reinforced a theme we continue to see across the communications industry: as networks become more programmable, and communications become more complex, accurate and current phone number intelligence becomes increasingly important. 

To make informed decisions, communications providers need to understand the context of the phone number.

From authentication to accountability

One of the clearest topics at SIPNOC was that authentication is about more than simply determining whether a call is legitimate.

The industry is continuing to build mechanisms that establish identity, authenticate communications, and create greater accountability across the network. Discussions throughout the event touched on STIR/SHAKEN, call analytics and vetting, traceback, delegated certificates, international authentication, and the challenges of combating evolving telecom fraud.

But authentication is only one part of the complicated equation.

To make informed decisions, communications providers need to understand the phone number itself: who is serving it, what type of number it is, where it belongs in the network, and how that information changes over time.

That is where phone number intelligence can provide an important foundation.

The programmable network needs intelligence

Dr. Marco Lafrentz, netnumber’s VP of Business & Market Development, explored this topic during his SIPNOC session, “The Programmable Network: Navigating Fragmentation in the Network API Era.”

As the industry moves toward programmable connectivity and technologies, such as GSMA Open Gateway and CAMARA APIs, the vision is compelling: applications can increasingly interact directly with capabilities exposed by communications networks.

The challenge is that global network capabilities are not deployed uniformly.

API availability, technical readiness, commercial models, and network connectivity can vary significantly between markets. For a multi-country enterprise, this complexity compounds quickly: identifying the right network, determining available capabilities, and routing each request accurately become mission critical.

Phone number intelligence can act as the connective layer.

Real-time information about a phone number can help organizations determine the appropriate network, understand available services, and make better routing decisions before initiating a transaction.

In other words, the programmable network still needs intelligence to know where to go.

Fraud is becoming a data problem

Another major thread running through SIPNOC was the continued evolution of telecom fraud.

As fraudsters adapt, the industry is moving beyond simple blocking and detection toward a broader model of identity, authentication, and accountability. SIPNOC’s 2026 program included discussions around AI-powered phone fraud, evolving robocall strategies, number fraud, and the operational realities of accountability in an All-IP environment.

This increasingly also makes fraud prevention a data problem.

The more accurately a communications provider can understand a phone number and its relationship to the network, the more information it has available to make decisions about trust, routing, authentication, and risk.

That is why current, authoritative telecommunications data matters.

Connecting the dots with phone number intelligence

For netnumber, SIPNOC highlighted how closely these issues are connected.

Authentication. Routing. Identity. Fraud prevention. Network APIs.

These may appear to be separate challenges, but they increasingly depend on the same underlying question:

What do we really know about this phone number?

netnumber provides real-time phone number intelligence designed to help communications providers answer that question.

From Carrier ID and Number Check to routing intelligence, STIR/SHAKEN support, and fraud mitigation, netnumber helps organizations turn complex telecommunications data into actionable intelligence.

As communications networks continue their transition toward All-IP and programmable connectivity, the need for that intelligence will only become more essential.

Looking ahead

SIPNOC 2026 made one thing clear: the communications industry is continuing to build a more trusted, programmable, and interconnected network; but achieving that vision requires more than new standards and APIs.

It requires the intelligence to understand the network behind every interaction.

At netnumber, that is the problem we have been solving for years.

Because when communications become programmable, knowing where the number belongs, and what it tells you about the connection, is more important than ever.
