Initially, everything worked perfectly: I could talk to the assistant normally, ask questions, and receive answers. After some time, I visited the website again. Since then, however, the assistant only says the greeting, and the conversation ends immediately. I can neither speak myself nor enter any information.

Probably your tools or system prompt is uses non-ascii supported char like curly/slanted " and ', or even •/→/—/– (not to be confused with -). Normalize the text. I had a similar issue.

Can you try switching the transcriber to Deepgram and test again? We’ve seen cases where this resolves the issue where the assistant greets and then immediately ends the conversation. Let me know once you’ve tried it.
