NTT DATA wins Microsoft Partner of the Year in Converged Communications

I’m thrilled to announce that NTT DATA has been named Microsoft Partner of the Year in Converged Communications. This honor celebrates our team’s innovation and the impact we make with Microsoft every day. 

Communication is at the heart of what we do, and this award strengthens our commitment to delivering secure, AI-powered collaboration for organizations everywhere. 

What is converged communications? 

Converged communications brings together all the ways people connect — voice, video, chat, meetings and collaboration — into a single, seamless experience. Rather than relying on separate systems for telephony, conferencing and messaging, organizations can unify everything through platforms like Microsoft Teams, backed by intelligent infrastructure and AI-powered insights. 

At NTT DATA, we take this concept further. Our Converged Communications portfolio integrates Cloud Voice, Operator Connect, Direct Routing, Managed Teams Meeting Rooms, and Managed M365 Productivity, all designed to deliver secure, reliable and intelligent collaboration at a global scale.

This convergence allows organizations to simplify their operations, reduce costs and give employees access to flexible, AI-enhanced tools. 

Global transformation in action: Siemens 

Our work with Siemens showcases the real-world impact of converged communications. Together, we executed a massive global transformation by supporting 35,000 users with telephony services.

By combining Operator Connect and Direct Routing in a hybrid deployment, Siemens achieved: 

• Over 20% annual cost savings
• AI-powered productivitythrough Microsoft Copilot for Teams  

Our AI-driven solutions have helped streamline operations across global Microsoft Teams services, leading to standardized workflows and sustainable cost reductions.

The NTT DATA advantage 

With over one million Microsoft Teams phone users managed globally across more than 40 countries, NTT DATA delivers intelligent experience management at scale.

Our expertise in hybrid voice solutions, global service delivery and AI-infused insights helps our clients achieve measurable results in performance, adoption and employee satisfaction. 

This recognition from Microsoft highlights the strength of our global partnerships and the dedication of our teams. We extend our gratitude to Microsoft and every NTT DATA colleague who continues to drive innovation, trust, and excellence in everything we do. 

Together, we’re redefining how the world works — through converged, intelligent and connected communications.
