Sure Selects Metaswitch Cloud Native VoLTE to Expand Reach of Voice and Data Services

Network modernization brings high-quality internet services to Indian Ocean islands

LOS ALTOS, Calif. – March 5, 2019 – Cloud native communications software leader Metaswitch today announced that international public telecommunications service provider Sure will deploy Metaswitch’s Clearwater cloud native IP Multimedia Subsystem (vIMS) core and VoLTE TAS solutions in the Diego Garcia region of the Indian Ocean, accelerating its cost-efficient transformation from circuit-switched telephony infrastructure to all IP.


The network transformation will enable Sure’s subscribers to take advantage of higher-speed, higher-performance 4G mobile while helping Sure to reduce its operational expenses through network functions virtualization (NFV). NFV enables providers to develop and deploy independent network components as pure software elements for increased agility, flexibility and performance.

“As a customer of Metaswitch for more than 10 years, we knew they were the right partner to provide us with the services we required within our budget,” said Sure CTIO Cyrille Joffre. “Their technology and cloud native architecture had the ability to ease our transition to new software-defined service function chains that are uniquely flexible, resilient and scalable. They also understood the deployment strategy supporting our key customers in Diego Garcia.”

Sure Diego Garcia is part of the Batelco Group, a leading telecommunications provider which operates in 16 markets spanning the Middle East, Northern Africa, Europe, the South Atlantic and the Indian Ocean. Sure Diego Garcia provides communications services for base personnel at the U.S. Naval Support Facility on Diego Garcia, an island within Chagos Archipelago in the Central Indian Ocean. The introduction of 4G services will be a big advance ensuring base personnel can easily keep in touch with family and friends back home.

Clearwater Core is Metaswitch’s implementation of IMS, built exclusively using cloud and web-scale development methods to provide voice, video and messaging services to millions of users. The service-based architecture inherent to Clearwater Core provides a much lower OPEX, being a fully orchestrated and automated solution. Clearwater Core is designed from the ground up for deployment in any environment: virtualized, public, private or hybrid elastic clouds, and combines the economics of over-the-top (OTT) style service platforms with standards compliance and reliability expected of telco-grade communications network solutions.

“With Metaswitch cloud solutions, Sure can transform its communications and bring cost-effective and advanced communications services to its customers in a remote area where these services otherwise would not be available,” said Chief Marketing Officer Ian Maclean of Metaswitch. “This deployment demonstrates our commitment to helping providers achieve true network transformation through NFV.”
