update_agent_config
Update an AI agent's configuration including name, language, voice, model, and variables. Only provided fields change; versioned agents save as draft.
Instructions
Update an agent's configuration (name, language, first message, voice settings, model, variables, etc.). Only provided fields are updated. To update the agent's prompt/instructions, use update_agent_prompt instead. For versioned agents, changes are saved as a draft — use publish_draft to make them live, or test the draft first via make_call with the draft's version_id.
