Why choose Intuity for Government Cloud Calling
US-based, US-personnel
Government cloud environments demand US data paths and US citizens support. That is how we operate.
Done-for-you migration
Licensing verification, tenant readiness, number porting, dial plans, and testing, handled end to end.
Weeks, not months
A defined three-step process takes you from license check to live calling without a research project on your side.
Consolidation offsets cost
Many clients fund the move with what license consolidation recovers.
What is GCC High?
How is it different from GCC?
GCC is Microsoft’s government version of Microsoft 365. GCC High is a stricter enclave built for controlled unclassified information and defense work.
For federal, state, local, and tribal entities and the contractors that serve them.
How does phone calling work in GCC High?
Direct Routing is the PSTN path for GCC High. Operator Connect and Microsoft Calling Plans are not supported in that environment, which surprises teams migrating from commercial Microsoft 365. Intuity operates the Direct Routing infrastructure, so your users get a dial pad in Teams that behaves exactly like commercial calling, inside an environment that satisfies your compliance obligations.

The compliance is mandatory. The overspend is not.
But most organizations we move end up spending less than they feared, because consolidating licensing under one partner surfaces unused seats, overlapping subscriptions, and plans mismatched to actual roles. Clients routinely fund a meaningful share of the voice upgrade with what consolidation recovers.
