London, UK, 3rd November 2022 – XConnect, a Somos Company, the provider of world-class numbering intelligence solutions has partnered with Cellusys, a leading telecom security solutions provider, to deploy XConnect’s Global Number Range (GNR) services for validating A-Numbers. Cellusys will deploy XConnect’s solution to enhance its customer platform with Origin Based Rating (OBR) surcharge and robocalling mitigation capabilities.

With XConnect’s GNR services, Cellusys gains the ability to ­protect against surcharges on both fixed and mobile voice traffic and proactively block invalid and fraudulent numbers with precision. The partnership enables Cellusys to strengthen its suite of signalling security solutions to provide an optimised customer experience.

“Pre-validating A-Numbers has become essential for delivering valid traffic, ensuring margins are protected, and removing identity risk. As the voice industry becomes more complex, dedicated solutions are needed to enable carriers to confidently terminate traffic,” said Tim Ward, VP of Number Information Services, at XConnect. “By working with Cellusys, we are removing spoof calling and unexpected surcharges for carriers. Together, we are combatting some of the toughest challenges facing the modern telco market.”

Cellusys designs and delivers solutions that give operators comprehensive control over their signalling, with a focus on roaming, security and analytical applications. It delivers systems to make mobile networks more secure, intelligent and profitable.

“Call fraud is a major problem for voice players in the telecoms industry. This is causing losses of margin in an already challenging market. Realtime detection and blocking is key to protecting revenues,” said Brendan Cleary, CEO, at Cellusys. “Our goal is to provide our customers with the latest signalling security innovations to prevent fraud instances and empower them to take back control of their networks. Through our partnership with XConnect, we are building an ecosystem to enable carriers to fight fraud and enhance their voice offerings.”


XConnect maintains one of the world’s largest number intelligence database, available via direct download or real-time, ultra-low latency number lookup queries. Its GNR data covers in excess of 11,000 operators in 232 territories and includes a dataset of 8.5 million range records.
