The issues you're describing—agent not checking available time slots via n8n, stopping when users provide extra details, or repeating questions—are typically related to your
Response Engine (LLM) configuration and
tool/function calling setup, rather than the voice agent settings themselves.
The available sources focus on voice agent creation and update parameters (voice settings, responsiveness, interruption sensitivity, etc.) but don't cover the specifics of LLM prompt engineering, tool calling configuration, or n8n integration troubleshooting. [(1) ](

For your specific issues:
1.
Time slot checking not working – This likely involves how your custom function/tool is configured in the Response Engine (Retell LLM) and how n8n is receiving/responding to those calls.
2.
Agent stopping or repeating questions – This is usually a prompt engineering issue or related to how the LLM handles unexpected input.
