ZIRO helps public sector agencies, education institutions, and regulated organizations modernize voice on Microsoft Teams Phone — and then takes the ongoing work off their hands. Rather than a telco-led migration followed by years of in-house administration, ZIRO operates as a platform partner, not a carrier, that plans the move, runs the cutover, and manages day-to-day voice operations — so internal teams don't have to build or staff a dedicated telephony function.

For public sector and regulated buyers, speed, certainty, and predictability matter as much as cost. ZIRO's platform-led discovery replaces weeks — or months — of spreadsheets and stakeholder interviews with rapid, automated assessment and clear readiness insights, so leaders can make confident decisions earlier and avoid project delays. Structured migration planning from legacy PBX environments reduces the manual, error-prone work that typically slows Teams Phone adoption.

Delivered as a managed service and hosted in Azure, ZIRO handles provisioning, administration, moves/adds/changes, and ongoing optimization through a single platform. IT teams gain centralized visibility into voice configuration, reporting, and governance, while helpdesks execute routine changes through role-based controls — keeping sensitive environments controlled and auditable, and reducing dependence on scarce voice specialists. 

Modernizing voice this way does more than retire legacy systems. Once voice lives natively in Teams, it becomes part of the same governed, AI-ready environment as the rest of Microsoft 365 — so when an agency is ready to extend Copilot and AI-driven workflows, voice is already a connected, structured input rather than a separate silo. ZIRO is built to make that connection, turning voice from an operational cost into a long-term strategic asset.

ZIRO is a Microsoft Teams-focused platform partner — not a carrier — recognized as a Teams Phone specialist and one of Microsoft's global Teams Phone Accelerator partners. From migration through daily operations, ZIRO helps public sector and enterprise customers accelerate Teams Phone adoption, strengthen governance, and keep voice working without the operational drag.
