Telnyx

Telnyx is a cloud communications platform that provides carrier-grade voice, messaging, and connectivity infrastructure for AI agents, applications, and global businesses. Its primary purpose is to give developers and product teams direct access to telecom-grade networks via APIs, enabling low-latency, high-quality voice and messaging experiences worldwide. Telnyx operates as a licensed carrier in multiple regions, which allows it to control routing, quality, and pricing more tightly than typical aggregators.

Key features include programmable Voice APIs, SIP trunking, and WebRTC-based real-time communications optimized for AI voice agents and contact centers. Telnyx offers global phone numbers (DIDs), number porting, call recording, call control (IVR, call forwarding, conferencing), and advanced routing with real-time media for speech recognition and synthesis. Its private, global IP network and edge infrastructure reduce latency and packet loss, which is critical for conversational AI and real-time customer support. Additional capabilities include SMS and MMS messaging APIs, emergency calling in supported regions, and detailed analytics for monitoring call performance and usage.
