Telnyx Launches Programmable Voice API: Call Control

Telnyx Call Control: Programmable Voice API

Call Control

Telnyx, the world’s only self-service, full-stack communications platform — with numbers in more than 60 countries around the globe — today announced its Programmable Voice API: Call Control. With enterprise-grade reliability, a full feature set, integration tools and documentation, the launch makes it clear that Telnyx is now an official contender in the CPaaS space.
As a software-driven licensed telecom operator with its own network, Telnyx offers 6,000+ business customers unprecedented access to and control of the very fabric of communications — the public switched telephone network (PSTN) — enabling them to build differentiated solutions and products not possible through other CPaaS providers or incumbent telecom operators.
Using the Call Control voice API, customers can build highly customizable calling experiences into their own applications. Key features include the ability to answer or transfer calls, play recorded messages, record calls, respond to prompts via keypad or voice, stream media to multiple recipients, automatically detect answering machines (AMD), manage conferences, and more.
One key advantage of Call Control is that developers don’t need telecom expertise to build voice applications. The platform executes all telephony functions, so developers can focus on designing an engaging calling experience. The use cases include: contact center and UCaaS platforms, cloud-based IVRs, call tracking solutions, AI applications, omnichannel routing and voice notifications and alerts. Any workforce application with embedded collaboration or communication requirements can leverage Call Control.
Telnyx’s solution is unique for a number of reasons. First, Telnyx manages a private network environment with control over call routing and core communications functionality. Using an edge-stack approach, Telnyx also leverages global PoPs to process data in the location nearest the customer application, which means inputs can be received, acted on, and then Telnyx can provide webhooks back to those applications in a fraction of a second.
Additionally, the Telnyx voice API can receive real-time commands throughout the call for interactive control. This is in stark contrast to most competitor solutions, which require pre-scripted commands at the beginning of a call. Telnyx customers can also stream call media to multiple recipients — including AI engines and contact center auditing agents — in real time. As a result, call media can be duplicated, delivered, analyzed and returned instantly.
Lastly, Telnyx developed an XML translator tool called TeXML Translator. TeXML Translator removes any barriers to switching from competitor XML-based solutions, allowing customers to build applications using Telnyx numbers — fast. Those that already have an XML application can simply configure their Telnyx portal connection to point at their XML endpoint. When a call comes in, Telnyx does the rest. Customers can also write new XML applications in minutes using simple TeXML commands.
The tool aims to make it fast and simple for customers wanting to integrate voice into their applications without the need for extensive development time and resources. In addition, Telnyx has developed SDKs in popular programming languages and application-based guides to further enable faster, streamlined customer migration.
“The Telnyx Call Control API offers more granularity than any competitor solution,” said Telnyx COO Ian Reither “Not only this, it’s built on our private, global IP network which means better call quality, end-to-end security and reliability. And for those wanting a fast, simple way to integrate voice into their apps — we’ve developed the tools to enable that too.”
Over the years, Telnyx has built a more robust offering through vertical integration — converging the CPaaS, telecom service provider and telecom equipment manufacturer business models. The company offers customers a secure, highly available platform that traditional operators cannot. It has deployed a global network, leverages a multi-cloud infrastructure, procures numbering resources directly from regulatory authorities, and interfaces with other carriers as a peer. Telnyx has outpaced competitors, while offering unique solutions for previously underserved areas of the market.
