Built on Microsoft. Tuned to your industry.
We move your phones to Microsoft Teams Phone and run them, planned around how your industry works.
Where voice does the heavy lifting
Many enterprises already pay for Teams Phone. It comes with Microsoft 365 E5 and E7. ZIRO turns it on and runs it. Once your phones run on Teams, they work with the rest of your Microsoft 365, including its AI.
Voice is the work. Caseloads, regulators and dispersed teams all run on conversations that have to be secure, recorded and reachable from anywhere. Dorsey & Whitney is moving 1,450 users across 18 sites off Cisco, and retired a contact center it didn't need along the way. We run it for them as they go.


Offices, remote sites and factory floors rarely share a phone system. Teams Phone puts them on one — and finally pays back the Microsoft 365 you already own. Oldcastle APG moved 1,126 users across 223 sites in six weeks, beat a contract deadline, and now saves $150K a year. We run it for them today.
Advice, risk and client trust move through voice all day. The bar is high: every nuanced conversation has to be clear, captured and compliant. Laurentian Bank moved 61 sites off Avaya in six months, after its support bill tripled to $900K a year. We run it for them today.


Districts and campuses carry big seat counts and tight budgets. Voice on Microsoft turns a cost center into something IT can actually run. SAIT moved 2,000 users across its campuses in six weeks, with zero downtime and its emergency phones kept live. We run it for them today.
The same approach, wherever you are
