Use Cases

Call Tracking and Marketing Attribution

You know voice experiences are the most important touch points for customers. With Telnyx, they’re the last thing you have to worry about.

Unmatched Performance

Build on the most reliable network in the industry. Our international points-of-presence pull call media off the public internet to keep calls private, secure, quick and clear.

Feature-Rich Ecosystem

Telnyx was built for applications like call tracking and includes features that traditional carriers will never provide, like embeddable number search, instant provisioning and real-time reporting.

Faster Development

Our fully-featured API includes intelligent number search, outbound calling and programmable SMS. Developers can go zero to global communications with interactive documentation and 24/7 support.

They Call, You Track, We Deliver

Built for Call Tracking

At Telnyx, our bespoke infrastructure was designed to support global communications in next-generation applications. We started with a private network spanning the globe and a state-of-the-art telephony engine, then we opened up our platform with a developer-tested API and a self-service configuration portal. Now we spend our days building new features, improving services and reducing costs for innovative service providers like you.

Global Numbers

Find numbers in over 20,000 North American rate centers and gain access to international numbers from 60 different countries. Provision any available toll-free number, find a particular vanity number or search for large contiguous blocks.

Reporting for Right Now

Our customers asked for robust reporting features, and we delivered. Flexible usage and spend reporting can give you real-time insight and help you narrow in on sales opportunities or customer issues. Our multi-tenant architecture was built for user platforms like yours.

I prefer Telnyx over Twilio for selecting phone numbers as they have much more flexibility in search features. Bulk searches, premium numbers, etc.
