Direct Routing with USTelco - FCC-Compliant Voice for Microsoft 365 Workforces

BYOC for Microsoft Teams

Microsoft Teams has become the communication hub for the modern enterprise. But native PSTN access through Microsoft Calling Plans can be limiting, expensive, and lacks the compliance controls that regulated industries demand.

USTelco enables secure, regulatory-grade Direct Routing into Microsoft Teams, allowing your organization to Bring Your Own Carrier (BYOC) and unlock full control over your voice infrastructure, without leaving the Teams environment.

“Leverage the power of Microsoft Teams. Let USTelco secure the voice behind it.”
