World Telecom Labs (WTL) today announced that it has developed a Lawful Intercept (LI) system for Brazilian operator, Vonex Telecom.

The LI will enable Vonex to respond quickly – and in accordance with the current legal guidelines in Brazil - to demands from law enforcement agencies to intercept voice calls to and from nominated businesses and customers.

Vonex is a long-time customer for WTL’s 2nd generation VoIP switches which are being used to manage the transfer of voice calls between Vonex’s VoIP network and other fibre and cellular networks in Brazil. A licensed operator in Brazil since 2005, Vonex is the leading provider of local voice services, national, international and long distance VoIP to business customers in Sao Paulo, Brazil’s largest city.

The provision of LI capability is often written into the license conditions of telecom operators around the world but in practice is not always delivered due to the cost and complexity of current solutions. However, in the face of increasing threats from terrorism and organised crime, the authorities in many regions are moving to tighten regulations.

After a request from Vonex, WTL developed and installed a software plug-in for its switches which enables voice calls to be split so that they are transmitted in the usual way with no interference and simultaneously diverted to the police to be recorded without the knowledge of either the caller or recipient.

A key requirement for Vonex was that the WTL system would work for both VoIP and legacy TDM calls (other solutions had required separate systems for the two traffic types which increased both complexity and cost).

Fadi Sleiman, President of Vonex said “Legal Intercept used to require the installation of expensive specialist equipment. However, World Telecom Labs rose to the challenge and provided us with a customised system. Its team of experts are always extremely helpful and technically sophisticated and I recommend them highly.”

WTL’s range of 2nd generation VoIP and hybrid VoIP/TDM switches have been deployed by a number of operators throughout South America, Europe, Africa, Asia and the Middle East. They have been specifically designed to replace the huge, expensive, maintenance-heavy switches that have traditionally been used to transfer VoIP traffic onto other networks. They are capable of handling 1000s of simultaneous calls and were recently named Most Innovative Product of 2014 at the 10th Nigerian Telecoms Awards.

WTL 2nd generation VoIP switches have been installed and integrated with Vonex’s proprietary CPEs. As well as intelligently routing calls to and from the appropriate outbound carrier, the switches use the latest techniques to increase capacity on Vonex’s existing network and enable it to both guarantee zero downtime and high quality VoIP calls for its growing customer base.

Leigh Smith, MD of World Telecom Labs, said “Every telecom operator is required to act on Government requests to intercept calls but the fact is that very few can – and those that can have had to buy, install and manage specialist systems. Our team of engineers are experts in the management, optimisation and transfer of VoIP calls. I knew that they would be able to rise to this challenge!”
