Call End Configuration - Zero Runtime

Call End Configuration controls when and how the agent ends a call, and whether it produces a summary afterwards. On the Agent tab, select Configure Call Ending.

Call Ending panel with the End Call Tool and Call Summary settings

End Call Tool

When enabled, the agent can end the call by itself once your conditions are met. It still ends the call when the caller asks directly.

Field	Description
Conditions (required)	When the agent should end the call, for example “End the call when the user says goodbye or confirms they have no further questions.” One condition applies to all languages.
Final Response (required)	The exact message the agent speaks before hanging up, for example “Thank you for your time. Goodbye!” Supports variables.

The Final Response isn’t translated automatically. Use the language selector inside the field to enter it for every configured language, or you won’t be able to save.

Call Summary

When enabled, the agent generates a summary and outcome report at the end of each call and sends it to your endpoint.

Field	Description
Large Language Model (LLM) (required)	The model that writes the summary. Models with the Inference badge need no API key. Other models ask you to choose a secret.
Summary Instructions (required)	What to include, for example “Summarize the key outcomes and next steps in 3-4 sentences.”
Summary Endpoint URL (required)	The URL the summary is sent to, for example `https://your-domain.com/webhook`.
HTTP Headers	Optional headers sent with the request, such as `Authorization: Bearer <token>`.
