Hello Sebastien,
Is this happening with regular frequency? I would recommend revisiting your instructions and modifying them to have more explicit instructions in your AVA's Guidelines section about maintaining language context during tool invocations. For example:
"When a tool is invoked after a language switch, ALL system messages including wait messages must be in the currently active language, not the default SIP trunk language."
If the bot is still reverting after instructions like the one above, you may want to open a case with Product Support to see why the AVA is choosing French for that comfort statement.
