What Each Special Area Shows
| Area | Evidence | Use it when |
|---|---|---|
| Retries | Parent call id, attempt rows, retry status, timing, and final result. | A recipient was called more than once. |
| Transfers | Transfer sessions, representative legs, bridge state, timing, and failure reason. | The agent attempted a human handoff. |
| Audio Cache | Cache status, hit rate, lookups, hits, misses, and new cache entries. | Repeated phrases felt fast, slow, or inconsistent. |
Audio Cache Metrics
The call detail Audio Cache tab reads the cache summary stored on the call when available.| Metric | Meaning |
|---|---|
| Cache Status | Whether Audio Cache was enabled for the call. |
| Cache Hit Rate | Percentage of lookups that reused cached audio. |
| Lookups | Number of cache checks for repeated text-to-speech segments. |
| Hits | Number of times DialNexa reused cached audio. |
| Misses | Number of times no matching cached audio existed. |
| New Cache Entries | Number of new synthesized segments stored for future reuse. |
If Audio Cache was disabled, the UI can still label some numbers as potential cache behavior when data exists. That helps users see whether a repeated script would likely benefit from turning it on.
Why Cache Misses Happen
| Cause | Example |
|---|---|
| Dynamic variables | ”Hi Rohan” and “Hi Priya” are different generated phrases. |
| Model wording changed | The LLM says the same idea using different words. |
| Voice configuration changed | Different provider, voice, voice model, speed, stability, volume, or output format. |
| Long custom replies | Long responses usually vary too much to repeat exactly. |
Transfer Evidence
Transfers should be reviewed as sessions, not just as a transcript moment.| Evidence | What it explains |
|---|---|
| Transfer session status | Whether handoff reached a final transfer state. |
| Representative leg | Whether the destination answered, failed, or timed out. |
| Bridge status | Whether caller and representative were connected. |
| Failure reason | Why the handoff did not complete. |
| Timing | Whether the transfer waited too long or failed quickly. |
