Release notes

gpt-oss-120b, OpenAI's open-weight reasoning model, is now hosted on Telnyx-owned GPUs in US regions on Telnyx Inference.

Enable auto_chunk_long_messages on a messaging profile and Telnyx splits oversized SMS into ordered, receipt-linked chunks instead of failing the send.

Deploy Pipecat voice agents to Telnyx Edge with one command and connect them to a Telnyx phone number.

Set up sending domains, build reusable templates, and validate recipient addresses directly in the Telnyx portal.

Send email through the Telnyx SMTP relay with the same domains, quotas, billing, and events as API sends.

Send and receive MMS over the MM7 protocol, the standard SOAP/XML interface used by carrier MMSCs and enterprise MMS platforms.

Dedicated sending IPs for high-volume email customers.

Give an AI agent its own isolated browser session through an API, limited to the sites you allow, so it can use websites that have no API.

Telnyx Number Lookup now returns the name and postal address behind a phone number with Caller Identity, plus Enhanced Caller Name with broader coverage than standard CNAM.

AssemblyAI Universal-3.5 Pro on Telnyx Voice AI Assistants now accepts a context prompt and keyterms, and receives the agent's last reply on every turn.

Telnyx Programmable Voice is now available in Mumbai, with local SIP connectivity through the Mumbai anchorsite.

Edge Compute functions can now call services on your private Telnyx WireGuard network through a network binding, joining the function as a peer on deploy.
