Ultimate Call Control

Get real time interactive command and control with the Telnyx voice API.


Advanced Calling Capabilities

Real Time Call Control

The Telnyx voice API allows for simultaneous bidirectional data transmission. Users receive commands dynamically throughout the call for granular-level, interactive command and control based on real time decision-making.

Super Low Latency

Our direct 10G network connections with all major CSPs mean Telnyx is able to control how data is routed for a more consistent experience. And, we leverage multiple global points of presence to process data in the location nearest your application.

Powerful SDKs

Our API wrappers allow you to easily integrate without having to build RESTful requests for each interaction. Get started fast with SDKs in popular programming languages including Python, Node, Ruby, PHP, Java and .NET, and more to come.

Granular Customization

While our TeXML Translator tool is designed for simplicity and compatibility, the Call Control API is designed to give you maximum flexibility and control. So, you can build exactly what’s required for your specific application.

Unmatched Developer Experience

TeXML is an XML based data structure you can use to build Call Control applications that are associated with your Telnyx phone numbers, fast. It’s the easiest way to get started with Call Control using a simple XML file.
