Release notes

Two new built-in insights score how well your AI Assistant follows instructions and how satisfied callers are, with no custom prompt engineering required.

Telnyx now offers United Arab Emirates as a data storage location and as an inference region. Store call recordings, transcripts, AI data, and usage logs in UAE infrastructure, and run open-weight...

AI Assistants can now call functions that run directly in the browser during a voice or chat conversation, with access to browser state, local data, and session-authenticated APIs without a webhook.

Voice AI Assistants can now tune how confident they must be that a caller genuinely wants to interrupt before stopping, so backchannels like "yeah" or "uh-huh" no longer cut the assistant off...

Define what your AI Assistant says to callers while a webhook tool call is executing, so callers never sit in silence.

Telnyx Voice AI now includes Arabic speech-to-text and text-to-speech model options for Arabic-speaking customer interactions.

Number Reputation lets you monitor the spam reputation of your outbound calling numbers across the major analytics networks US carriers use, and remediate flagged numbers before they hurt your answer...

Branded Calling displays your verified business name, logo, and call reason on the recipient's screen before they answer, so more of your outbound calls get recognized and answered.

AI agents signing up to Telnyx without an email now get a durable inbox by default, powered by AgentMail, so autonomous AI agents can complete signup and verification with no human in the loop.

GLM-5.2 by Z.ai is the highest-ranked open-weight model on Artificial Analysis, now hosted on Telnyx-owned GPU infrastructure.

Telnyx Inference can now persist and semantically search conversation records across supported Telnyx communication sources, starting with Voice (SIP).

Inworld Realtime TTS 2 is now available through Telnyx APIs and Voice AI Assistants, extending expressive realtime voices to both standalone API usage and managed agents.
