Case Study: a large US government organization modernizes telephony with VOSS Solutions

Implementing Microsoft Teams for a Large Government Department

The large US government organization faced significant challenges in transitioning 150,000 users from a legacy Cisco PBX to a unified Microsoft Teams Phone system. The complexities included managing a single, massive Microsoft 365 tenant for multiple unique agencies, coordinating the coexistence of two telephony systems, and handling the immense technical scale, all without the ability to retrain its widespread service desk teams. To address this, they engaged VOSS Solutions.

VOSS Solutions implemented its VOSS Automate provisioning platform, which was already managing the existing Cisco system, to automate and streamline the migration. The solution provided a single portal for managing the mix of technologies, segmented the tenant into manageable hierarchical units for each agency, and enabled over 1,000 administrators to perform tasks without direct access to complex Microsoft admin centers. This allowed for a swift, cost-efficient transition with accurate, automated reporting and no need for retraining, successfully handling the project's enormous scale and complexity.
