Call ended with silence-timed-out without silence fillers.
We’re seeing an increased rate of silence-timeouts since switching to Gemini 2.5 Flash (Through custom-llm)
Example: Call ID
The agent did not play any configured silence fillers (e.g. “I’m having a hard time hearing you…”).
Instead, the call auto-timed-out during a long silence.
End-of-call report confirms silence fillers are configured.
Vapi logs show the LLM responded with “Great, What’s your first name?”, but this was never sent on the call, leading to a timeout.
I also ran test calls today, and silence fillers did work, so this seems intermittent.
Could you help investigate why the LLM response wasn’t sent and why silence fillers didn’t trigger in this call?
