Fully-managed, compliant Microsoft Teams Phone calling for GCC High — deploy in as little as a day,
Atlantech Online enables secure, compliant Microsoft Teams PSTN calling and audio conferencing inside Microsoft 365 GCC High — built for federal agencies, DoD contractors, and any organization handling Controlled Unclassified Information (CUI) or ITAR-regulated data. As one of the few carriers authorized to deliver Direct Routing voice into GCC High, Atlantech gives your organization enterprise calling, call queues, dynamic E911 location routing, secure PSTN dial-in/out audio conferencing, and cloud fax — fully integrated with your existing M365 GCC High tenant, with no on-premises hardware to buy or maintain.
How we implement it: Every deployment follows a three-step, white-glove process managed end-to-end by Atlantech's in-house team. First, Discovery & Design: we assess your GCC High tenant, user base, and technical requirements to design a solution tailored to your environment. Second, Implementation: our certified specialists configure Session Border Controllers, number porting, and Teams Direct Routing to meet Microsoft's encryption and regulatory requirements. Third, Go-Live & Support: deployment speed is driven by automation, not by us — turnaround can be as fast as a single business day, though the pace is ultimately set by the client's own readiness and rollout preferences. Once live, you're backed by comprehensive training and ongoing support from day one.
