Call quality signals
Every SIMCOAI call records how it actually went. These are measured during the call, not inferred afterwards.
The six signals on every call
| Signal | What it means | What good looks like |
|---|---|---|
| First reply | How long SIMCOAI took to start speaking after the caller finished | Under 1.2s reads as fast; up to 2.5s acceptable; beyond that sluggish |
| Caller turns | How many complete things the caller said | A proxy for how involved the conversation was |
| Interim results | Partial speech captured while the caller was still talking | High counts on a short call can indicate background noise |
| Interruptions | How many times the caller spoke over SIMCOAI | Occasional interruptions are normal conversation |
| Ended by | Who finished the call | Caller, SIMCOAI, or you from the dashboard |
| Finish reason | How the call concluded | For example completed or transferred |
What "stale response prevented" means
This is the signal most often misread. It does not mean something went wrong - it means something went right.
When a caller interrupts, SIMCOAI has usually already started composing a reply to what it heard before. That reply is now out of date. SIMCOAI cancels it rather than playing it, and listens to the new input instead. Seeing this on a call means the interruption was handled correctly and the caller was not talked over with a stale answer.
If first reply latency is consistently high
The usual causes, in the order worth checking:
- Check the modelPremium models can be slower. Compare a few calls on different model settings.
- Trim the knowledgeVery large uploaded documents take longer to search. Keep answers focused.
- Compare across daysOne slow call is not a trend. Look at the pattern across a day of traffic.
