How to combat telephone fraud with CAMARA APIs: Quobis’ proposal at MWC26

Phone fraud and spoofing have become one of the biggest challenges for network operators and businesses in 2026. In this context, Quobis returns to Mobile World Congress (MWC26) to present a disruptive solution: the integration of Quobis Caller Score with the CAMARA project’s network APIs.

If you’re attending the congress in Barcelona, ​​we invite you to visit us at the Spanish Pavilion to see this technology in action. If you won’t be at MWC26, we can give you a private demo at another time.

What is Quobis Caller Score and why is it vital today?

Quobis Caller Score is our reputation engine designed to identify and block malicious calls before they pose a risk. At this year’s MWC, we combined our technology with carrier APIs based on the CAMARA project, demonstrating the flexibility of our solution in combining different information sources to combat phone fraud.

Thanks to this integration, our solution can directly query network capabilities in real time, allowing for much more robust caller ID verification and extremely accurate risk scoring.

Deployment flexibility: Open Source or solutions from leading manufacturers

One of the great advantages of Quobis technology is its infrastructure agnosticism. We understand that every operator and company has a different ecosystem, so we designed Caller Score to be completely versatile:

• Open Source Environments: We can implement Caller Score on leading open source elements such as Kamailio, allowing organizations to maintain full control over their technology stack.
• High-Performance Private Environments: For deployments that require specific integration with traditional providers, our solution adapts seamlessly.

Quobis Caller Score Demo at MWC26: Quobis + Oracle (OCCAS)

For the live demonstration at our booth, we will be showcasing a Caller Score implementation on the Oracle Communications Convergent Application Server (OCCAS).

This technical demo will allow attendees to observe how Quobis security logic is integrated into a critical Oracle environment to protect real-time communications, using network APIs to validate each call.
