Cost-effective Teams Enterprise Voice Calling

Unify your Microsoft Teams with PSTN calling through the Telnyx network via two connectivity options.

Cloud-first customers prefer to enable Teams enterprise voice via Operator Connect, which allows you to integrate new and existing 3rd party telephony infrastructure in just a few clicks.

Administrators with complex on-premise or regulatory needs prefer Direct Routing, which gives greater control, full legacy integration and no per-seat charge.

Either way, you’ll benefit from a high-quality voice network designed for real-time communications which runs on a robust multi-cloud stack.
