Release notes

Voice quality can make or break your AI agent experience. Telnyx now offers ResembleAI voices, built on the Chatterbox model (ranked #1 open source Voice AI), delivering speech that preserves emotion, style, and accent.

175 Agent Skills teach AI coding assistants (Claude Code, Cursor, Windsurf) how to use Telnyx SDKs correctly — no more hallucinated API calls.

Telnyx Voice AI Assistants now support Anthropic Claude Haiku 4.5 as a native model option. Developers can deploy the model without managing Anthropic API keys, while still retaining the option to bring their own credentials.

Customers without a federal Tax ID (EIN) can now register for 10DLC messaging through the new Sole Proprietor brand type. Freelancers, small business owners, and individuals can complete registration directly in the Portal or via API.

Telnyx Cloud Storage is now available in Europe with the launch of eu-central-1. European customers can now store data closer to their users and AI infrastructure.

We are excited to announce that Deepgram is now available as a Speech-to-Text (STT) provider for file-based recording transcription on the Telnyx platform.

We’ve expanded our noise suppression offering by integrating Krisp-powered noise suppression into Telnyx voice workflows. This gives you another tool to improve audio clarity across real-world environments, whether you're building with the Voice API, deploying Voice AI Agents, or handling high-volume contact center traffic.

Know exactly what you’re paying for: telephony, inference, and transport.

New noise suppression settings are now available at the connection level for IP, FQDN, and Credential SIP connections. Customers can configure advanced AI-powered noise suppression engines and fine-tune attenuation levels directly from the Mission Control Portal or via the API.

Execute webhook tools asynchronously and deliver results to AI assistants mid-conversation using message injection APIs.

Four new special destinations are now available in the Outbound Voice Profile settings. Customers can now control whether they allow calls to these additional international destinations directly from the Mission Control Portal or via the API.

elnyx is now a certified SIP trunk provider for Yeastar P-Series PBX systems, enabling seamless integration with pre-configured templates for both Cloud (PCE) and Self-hosted (PSE) deployments.
