Migrating 11,000 users to Microsoft Teams Voice across 5 regions
Customer Overview
Konekt (Formerly Nuvias UC) partnered with a global leader in climate technologies during a pivotal moment in their digital transformation journey.
The customer’s requirements were both complex and extensive:
> Migration of 11,000 users from legacy PBX systems to Microsoft Teams Voice.
> Integration of analogue devices and bespoke solutions.
> Deployment of Microsoft Calling Plans in North America and Europe.
> Implementation of Teams Direct Routing.
The challenge
The sheer scale of the project brought significant hurdles.The customer had already experienced stalled progress with other providers, which had led to a degree of scepticism. At the same time, the complexity of coordinating thousands of users across multiple regions with diverse telephony requirements added another layer of difficulty. With more than 20 internal technicians involved, maintaining consistency and direction was critical.
Initially, the customer engaged with several providers, including large ITSPs and one of the world’s biggest consulting firms. However, these efforts stalled due to prolonged processes, limited progress, and a lack of trust.
What Konekt did
Konekt approached the challenge differently. We offered professional services on a monthly retainer basis, providing one dedicated full-time equivalent (FTE) consultant to guide the project forward. With no rigid milestones but a clear mission, our consultant became the driving force to unblock bottlenecks, accelerate migration timelines, and ensure smooth integration across regions.
Konekt overcame these obstacles by building trust through transparency and consistent delivery, offering strong technical leadership, and providing a single point of contact who ensured focus and continuity throughout the entire project.
The outcome
From March 2024 to March 2025, the consulting engagement has enabled the customer to make tangible progress in their IT transformation. They are now on track to complete their migration to Microsoft Teams Voice, with a future-proof environment that integrates seamlessly across regions. The project has allowed the organisation to foster collaboration globally, establish efficiency at scale, and finally achieve meaningful outcomes after previous attempts with other providers had failed.
This success illustrates how even a single dedicated expert, backed by the wider Konekt team, can deliver the expertise, continuity, and focus required for complex international projects.
This enabled the customer to accelerate transformation and deliver a scalable global communications environment.
