This is a submission for DEV's Summer Bug Smash: Smash Stories powered by Sentry.

The bug report was: "it says hello, then it goes deaf."

My AI receptionist answers a real landline. Caller dials, agent greets them properly, caller says "hi, I'd like to check my booking" and then nothing. Forever ♾️. The call stays connected. No error, no exception, no warning. The WebSocket to our speech provider sits there wide open, healthy, receiving audio, and the agent has simply stopped existing.

Turn one worked. Turn two never happened. Every time.

The wrong week
