Microsoft GCC High for Defense, Federal Agencies & DoD Contractors
Getting GCC High live is one thing. Making your whole voice estate work properly is another.
Aura understands the infrastructure, dependencies and real-world complexity behind enterprise voice and how to bring it together in GCC High.

TALK TO SOMEONE WHO KNOWS VOICE
Don't design GCC High voice around assumptions.
15-minute conversation. Real answers. A path forward.

WHY AURA?
GCC High expertise is one thing.
Voice expertise is another. You need both.
Knowing GCC High is not the same as knowing enterprise voice.
Making the full voice environment work takes a different level of experience.
Microsoft knowledge without deep telephony expertise.
❌ Not enough
Voice expertise without GCC High understanding.
❌ Not enough
Technology without migration and operational support.

GCC HIGH TEAMS PHONE
The tenant is only half the story. Voice has to connect to the real world.
Aura’s GCC High voice services are built for DoD contractors, federal agencies and organizations handling CUI - where compliance, resilience and existing infrastructure all have to work together.
SBC architecture
Secure the boundary between Teams, PSTN and your existing communications environment.
PSTN & number services
Plan carriers, numbers, porting and routing around the locations and users that actually need them.
Emergency calling
Build emergency calling into the architecture from the beginning - not after deployment.
Local survivability
Keep critical locations communicating when cloud or WAN connectivity is unavailable.
Existing systems
Connect PBXs, analog, DECT, elevator phones and more, rather than forcing unnecessary replacement.
Policy & routing
Bring identity, policy, routing and infrastructure into one intentional operating model.
Contact centers
Integrate existing or Teams-native contact center environments without breaking customer operations.
Compliance & recording
Account for recording, retention and policy requirements as part of the voice design.
GCC & GCC High exists for a reason.
Commercial Microsoft 365 and even standard GCC don't satisfy the controls your contract actually requires. Here's where contractors get caught out.
CUI
Controlled information changes the architecture.
Microsoft positions GCC High for organizations handling DoD CUI and workloads requiring increased sovereignty and isolation. Your communications architecture needs to respect the same boundaries.
ITAR
ITAR is about control, not a checkbox.
GCC High supports organizations with ITAR obligations through US data residency and restrictions on access to customer content. Microsoft specifically provides ITAR contractual commitments for GCC High.
CMMC
GCC High does not make you CMMC compliant.
It provides capabilities that can support CMMC Level 2 and Level 3 requirements when appropriately configured. Your configuration, operating controls and processes still matter.
DFARS
The requirement follows the information.
For organizations working under applicable defense contracts, the Microsoft environment, communications architecture and operational model need to support the controls your contract requires. Microsoft lists GCC High as supporting DFARS requirements.
BUILT FOR ENVIRONMENTS THAT CAN'T AFFORD TO GUESS
This isn't our first complex voice environment.
30+ years of voice expertise
Deep enterprise telephony knowledge before Teams existed and Microsoft expertise for where communications are going next.
Microsoft Solutions Partner
Microsoft Solutions Partner. Operator Connect certified*. TX-RAMP certified. Proven GCC/GCC High voice expertise.
Ribbon Super Partner
Secure SBC, survivability and on-prem integration expertise for mission-critical communications.
Automated deployment
Reduce manual provisioning errors, lower professional services costs, and get GCC High voice live faster.
Common questions
Before you make the move.
Yes. In GCC High, Microsoft Teams Phone is delivered using Direct Routing. Aura designs and manages the voice architecture around it.
No. GCC High provides capabilities that can support CMMC requirements, but compliance also depends on configuration, implementation and operational controls.
Yes. Aura’s approach is Microsoft-first, not Microsoft-only. Existing communications can be integrated and migrated at the pace that makes operational sense.
Yes. Aura works with Ribbon technologies to design Teams environments with local survivability where continued communications are mission-critical.
It depends on your contractual requirements, data types and compliance obligations. GCC High is designed for organizations handling requirements such as DoD CUI and ITAR, but that decision should be based on the specific requirements that apply to your organization.
Automation reduces the manual work involved in provisioning, which helps cut configuration errors, lowers professional services effort and costs, and gets your GCC High voice environment live faster.
