The call was not from "the court". It is not part of the judicial process. It is without prejudice, meaning it is confidential and cannot be used in court.
However, for future reference, never, ever offer to pay a nominal sum if you don't believe you are liable at all. That is as good as an admission of liability, if it is outside of a non-prejudicial context.
You have already been advised that if you follow the advice and don't deviate by adding your own offers or suggestions, you will not be paying a penny.
