Telecom operators can now achieve significant cost savings and deliver superior call quality through the use of CRDB ENUM lookups. This real-time technology optimizes call routing by accurately identifying the correct network for each call, reducing unnecessary transit fees, and minimizing latency. The result is not just lower operational costs but also clearer, more reliable connections for customers.

These benefits are made possible by a strategic partnership between Redworks, RGTN’s Dutch subsidiary and a licensed Fixed Network Operator (FNO) and Mobile Virtual Network Operator (MVNO), and COIN, the Dutch organization responsible for managing number portability and database services.

The Challenge: Managing Call Routing Costs

Routing telephone calls always involves a balancing act between cost and quality. The most affordable option is to direct calls through the correct operator’s network. However, when the destination network isn’t clearly identified, calls may be routed through more expensive transit paths. This ensures the call connects correctly, but it increases costs and can also degrade call quality.

Before the introduction of CRDB ENUM lookups, operators relied on daily downloads of number databases to guide routing decisions. While effective to some extent, this method introduced delays and potential inaccuracies, particularly when numbers were ported between providers.

The Solution: Real-Time CRDB ENUM Lookups

To overcome these challenges, Redworks partnered with COIN to implement real-time ENUM lookups using CRDB (Central Reference Database) technology. This allows telecom providers to instantly identify the correct network for each call, optimizing routing in real-time.

RGTN CEO Leonardus Herps explains, “In the United States, ENUM-based real-time checks are standard practice, ensuring that operators always have the most accurate information. We’ve now brought this capability to the Netherlands, and the results speak for themselves—significant cost savings and improved call quality.”

How ENUM Lookups Benefit Your Business

With ENUM lookups, operators can:

1. Reduce Costs: By identifying the correct operator for each call, providers avoid unnecessary transit fees. This leads to substantial savings, especially for high-volume call traffic.
2. Enhance Call Quality: Direct routing minimizes latency and potential points of failure, ensuring clearer, more reliable connections.
3. Offer Lookup Services: Beyond using ENUM for internal optimization, providers can offer lookup services to their customers, adding a valuable revenue stream.

A Seamless Integration Process

The collaboration between Redworks and COIN didn’t happen overnight. Leonardus Herps recounts, “When we first discussed this with COIN, we realized they had the necessary functionality, but it was primarily used for testing. We decided to refine it together.”

Over several months, the teams from Redworks and COIN worked closely to integrate ENUM lookups into their systems. “We both knew exactly what ENUM needed to do, which made the collaboration smooth. There were minor bugs, but they were quickly resolved, and we experienced no significant downtime,” says Herps.

Even while still in the testing phase, Redworks fully transitioned to using ENUM lookups—and the benefits were immediate. “We saw a clear difference in our procurement invoices. The savings were substantial,” Herps notes.
