Retries, Transfers, and Audio Cache monitoring explain special behavior around a call. Retry history explains repeated attempts, Transfers explains human handoff sessions, and Audio Cache explains whether repeated speech was looked up or reused.
When a call has special behavior, the transcript is chapter one. The extra tabs are where the plot twists live.

What Each Special Area Shows

AreaEvidenceUse it when
RetriesParent call id, attempt rows, retry status, timing, and final result.A recipient was called more than once.
TransfersTransfer sessions, representative legs, bridge state, timing, and failure reason.The agent attempted a human handoff.
Audio CacheCache 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.
MetricMeaning
Cache StatusWhether Audio Cache was enabled for the call.
Cache Hit RatePercentage of lookups that reused cached audio.
LookupsNumber of cache checks for repeated text-to-speech segments.
HitsNumber of times DialNexa reused cached audio.
MissesNumber of times no matching cached audio existed.
New Cache EntriesNumber 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

CauseExample
Dynamic variables”Hi Rohan” and “Hi Priya” are different generated phrases.
Model wording changedThe LLM says the same idea using different words.
Voice configuration changedDifferent provider, voice, voice model, speed, stability, volume, or output format.
Long custom repliesLong responses usually vary too much to repeat exactly.

Transfer Evidence

Transfers should be reviewed as sessions, not just as a transcript moment.
EvidenceWhat it explains
Transfer session statusWhether handoff reached a final transfer state.
Representative legWhether the destination answered, failed, or timed out.
Bridge statusWhether caller and representative were connected.
Failure reasonWhy the handoff did not complete.
TimingWhether the transfer waited too long or failed quickly.

Investigate A Special Call

1

Open the original call row

Keep route, agent, batch, workflow, and call id context together.
2

Check retry history

If the call came from a batch, inspect attempts before judging the final recipient outcome.
3

Open Transfers

Review session state, representative leg state, bridge behavior, timing, and failure reason.
4

Open Audio Cache

Review cache status, hit rate, lookups, hits, misses, and new cache entries.
5

Fix the owning setting

Change retry rules, transfer configuration, voice setup, or Speech Settings based on evidence.

Retries And Statuses

Configure campaign retries.

Call Transfer

Configure handoff behavior.

Text To Speech

Understand cache-friendly speech.
