The API documentation shows you can update the Retell LLM configuration including general_prompt using the Update Retell LLM endpoint [(1) ]() , but it doesn't specify the behavior for calls already in progress at the time of the update.
Typically, ongoing calls use the configuration that was active when the call started, but I can't confirm this definitively from the available sources.
Check out these potentially useful sources:
- [Update Retell LLM]()
- [Documentation]()
- [Hire certified Retell partner]()
Would you like me to try to answer generally based on my knowledge instead?AI Evy
