Changelog

11.1.10 adds OpenRouter as an LLM vendor, a vendorParams object for sending vendor-specific parameters to the LLM from the agent verb, and Giggy as a speech-to-text vendor. Agents can now run without speaking (for driving DTMF-only IVRs), and they no longer speak stage directions such as “(silence)” or <think> blocks. Applications can send events, text, DTMF and variables into a running Dialogflow CES session without restarting the dialogflow verb. The release also stops a paused listen stream from leaking keypad digits, and fixes REST call updates that were refused before they reached the feature server.

New Features & Improvements

1. OpenRouter — openrouter is available as an LLM vendor, with credentials in the portal and API and a model list taken from OpenRouter’s live catalog. One OpenRouter key reaches models from Anthropic, OpenAI, Google, Meta, DeepSeek, Qwen and others. See OpenRouter.
2. llmOptions.vendorParams — the agent verb passes llm.llmOptions.vendorParams through to the LLM request, so you can use a vendor’s own parameters without jambonz having to support each one: OpenRouter provider routing and model fallbacks, OpenAI reasoning_effort and service_tier, Gemini thinkingConfig and safetySettings, DeepSeek thinking, Groq reasoning_effort, and others. It applies to OpenAI-compatible vendors and Google Gemini; Anthropic and Bedrock ignore it. The vendor pages list the parameters most useful for voice, including how to turn off reasoning to cut latency: OpenAI, Google, DeepSeek, Groq and OpenRouter.
3. Giggy speech-to-text — giggy, already a text-to-speech vendor, is now available for speech-to-text too, with interim and final results. A Giggy credential can be used for STT in the portal. See Giggy.
4. Agent speak: false — an agent with speak: false never sends its text to text-to-speech. Its text still goes to the history, llm_response events and the transcript. Use it for an agent that navigates a DTMF-only IVR, where any spoken word could be taken as a menu choice. Tool filler and early generation are off with it.
5. Agent speechCleanup — models sometimes write “(silence)” or “[No response needed]” when they mean to say nothing, and some emit <think> blocks; both used to be spoken. The agent now drops a paragraph that is only a parenthesised, bracketed or starred aside, and any <think>, <thinking> or <reasoning> block, before text-to-speech. A reply with nothing left to say ends the turn silently. History and transcripts keep the raw text. It is on by default; set speechCleanup: false to turn it off.
6. Dialogflow CES input mid-session — the websocket command dialogflow:update, or dialogflow_update in a REST call update, sends an event, text or dtmf and optional variables into the running CES session. Previously the only way was to redirect to a new dialogflow verb with a welcomeEvent, which restarted the session and reported a false caller hungup to the actionHook. Variables and DTMF are sent at once; an event or text is held until the agent finishes its current reply. The new input-sent and input-dropped eventHook events report what happened to held input.

Bug Fixes

• Keypad digits during a paused listen — while a listen stream with passDtmf was paused (for example with pauseCallRecording during a card payment), each digit was still sent to the websocket, written to the debug log and named in a trace span. While paused, digits are no longer sent, and neither the log nor the span contains them.
• REST call updates — the REST API refused a call update whose only option was llm_update, agent_update, llm_status, llm_tool_output, conf_listen_status, stt_reconfigure, room_say or room_play, with “no valid options supplied to updateCall”, so the update never reached the feature server. All are now accepted.
• Licensing banner — account users on a licensed system could see a false “unlicensed” banner in the portal.

Deprecations

• llmOptions.reasoningEffort on the agent verb was never implemented and has no effect. It is still accepted, so existing applications keep working, and the feature server now logs a warning when it is set. Use the vendor’s own parameter in vendorParams instead, for example {reasoning_effort: 'low'} for OpenAI.

Upgrade Notes (self-hosted)

• Database — 11.1.10 makes no schema changes; the upgrade only records the new version.

Component Versions

pcap-server and heplify-server 1.0.5 change only how they are built; they behave the same as 1.0.4.
