Release notes

Telnyx has launched HD Voice in Australia, introducing wideband audio for richer, more natural-sounding VoIP calls. Businesses can now deliver clearer conversations and a higher-quality calling experience for their customers.

Telnyx now lets you appeal rejected 10DLC campaigns directly in Mission Control Portal or via API, helping you resolve compliance issues faster and get campaigns approved sooner.

You can now connect Telnyx AI Assistants to any OpenAI-compatible API endpoint, including Bedrock, Azure OpenAI, or self-hosted inference servers. Bring your own LLM while keeping Telnyx’s real-time voice orchestration and low-latency pipeline.

Telnyx Verify and Verified Numbers now support DTMF extensions, enabling verification of phone numbers behind IVR systems. Automatically navigate IVR menus to complete verification calls without manual intervention.

Streamline your SMS campaigns and cut costs by automatically targeting only mobile recipients, eliminating wasted messages on undeliverable landlines.

Quickly verify if a number supports RCS before sending. Telnyx’s new RCS Capabilities Check API helps you route messages smarter, reduce fallbacks, and improve delivery success.

Create and register your own verification message templates directly in Verify for faster, more flexible deployments.

Telnyx now supports real-time webhooks, giving your application instant updates on verification statuses without the need for polling.

Telnyx Voice AI agents now give you full control over response timing with the new Start Speaking Plan. Configure context-aware wait times for punctuation, pauses, or number sequences so your agent responds naturally and never interrupts users mid-sentence.

Telnyx RCS now supports the message.read webhook, giving businesses real-time read receipts and complete visibility into message engagement.

We’ve added built-in geolocation support for emergency calls (911/933). Devices can now pass latitude and longitude in SIP headers, and Telnyx automatically constructs a PIDF-LO and delivers it to emergency services.

Improving accuracy, standardization, and visibility across porting workflows
