Release notes

We’ve expanded our Deepgram integration to support both TeXML and the Voice API, so you can add high-performance speech-to-text to any voice workflow. This builds on top of our existing Deepgram integration and Telnyx AI Agent integration.

Telnyx Voice AI Agents now support configurable background audio, letting you add ambient noise for more realistic experiences.

Telnyx Voice AI Agents now support warm transfers, allowing real-time handoffs between agents with conversation context included to avoid repeated information and improve call flow efficiency.

We’ve made some solid upgrades to media streaming that give you more flexibility when working with real-time audio, especially when you’re connecting to AI platforms or anything that expects audio in a specific format.This change removes a common integration headache and eliminates the need for additional audio transcoding. It simplifies your setup and cuts down on latency, complexity, and resource usage.

Telnyx now supports GPT-5 and Groq gpt-oss-120b for Voice AI Agents, delivering more choice, faster responses, and cost-efficient performance for real-time voice.

The Telnyx TypeScript/React Library gives developers full control to build custom Voice AI Agent widgets with low-latency, multimodal support.

We’ve expanded again to give you more ways to connect with customers across the globe. Telnyx now supports local outbound calling in 80 countries, with 3 new additions: Pakistan, Honduras, Mozambique

Telnyx Voice AI Agents now support receiving MMS messages during live calls. Users can send images mid-conversation, and the agent will interpret and respond instantly using a vision-enabled model like GPT-4o or LLaMA 4 Maverick.
