What Is Telnyx?

Telnyx is an AI Communications Infrastructure platform that provides a single, integrated API for:

• Voice AI - Programmable voice with Call Control, IVR, recording, conferencing, and WebRTC.
• SMS & MMS - Send and receive messages globally with delivery receipts and webhook events.
• SIP Trunking - Connect your existing PBX with elastic SIP trunks, failover routing, and codec control.
• AI Assistants - Deploy LLM-powered voice and messaging agents with built-in telephony.
• IoT & SIM - Global IoT connectivity with SIM management, eSIM provisioning, and data monitoring.

Unlike stitching together multiple vendors into a Frankenstack, Telnyx gives you one platform, one API key, and one bill. Calls and messages traverse the Telnyx-owned private IP network for lower latency and higher reliability.

How to Get a Telnyx API Key

1. Sign up at portal.telnyx.com.
2. Navigate to API Keys in the left sidebar.
3. Click Create API Key and copy the key.
4. Add it to your .env file as TELNYX_API_KEY=your_key_here.

Telnyx offers free trial credit for testing.

FAQ

Q: What programming languages are supported?

These examples cover Python, Node.js, Go, and Ruby. Telnyx also provides official SDKs for Java, PHP, and C#.

Q: Are these examples production-ready?

Yes. Every example includes error handling, environment-based configuration, and Telnyx webhook signature verification. Review security and scaling considerations before deploying to production.

Q: How is Telnyx different from Twilio?

Telnyx is an AI Communications Infrastructure platform with a private global network. It offers integrated voice, messaging, AI, SIP, and IoT under one API - no need to stitch together multiple vendors. Telnyx also offers significantly lower pricing with no per-seat fees or contracts. See a detailed Telnyx vs Twilio comparison.

Q: Do I need multiple vendors for voice, SMS, and AI?

No. Telnyx provides voice, SMS/MMS, SIP trunking, AI assistants, and IoT SIM management through a single platform and API key.

Q: Can I use these examples with my existing PBX?

Yes. The SIP trunking examples show how to connect Telnyx to Asterisk, FreeSWITCH, 3CX, and other PBX systems.

Q: Is there a free tier?

Telnyx provides trial credit when you sign up. After that, pricing is pay-as-you-go with no minimums or contracts.
