Telnyx

Telnyx is a global communications platform providing carrier-grade voice, messaging, and wireless data through a private fiber backbone.

Telnyx bypasses the public internet by operating its own global IP network (AS54538) to deliver low-latency connectivity for mission-critical applications. Developers use their RESTful APIs to provision numbers in 100+ countries, deploy cross-border IoT SIMs, and integrate AI-driven voice features. By acting as a licensed carrier rather than a simple aggregator, the platform offers granular control over call routing and real-time telemetry for over 1,000 global partners.
