Where Results Appear
Post-call fields become operational data after the call.Call detail custom section
Custom extracted values appear on the call detail page.
CSV exports
Exports can include extracted fields for reporting.
Workflow decisions
Workflow paths can reason about call attributes when configured.
QA review
Annotations and transcript review can explain why a field was wrong.
Post-Call Extraction LLM
The Post Call Analysis panel includes a model settings control for the LLM used by post-call extraction. This is separate from the live conversation model so teams can tune completed-call extraction without changing how the agent speaks during the call.
| Setting | Behavior |
|---|---|
| Default | DialNexa selects GPT-4.1 when it is available. |
| Allowed dashboard choices | GPT-5.4 Mini, GPT-5.4 Nano, GPT-4.1, GPT-4.1 Nano, and GPT-4o Mini. |
| Published versions | Published versions can disable edits. Update a draft version before changing extraction fields or extraction model. |
| API field | Integrations can set post_call_analysis_llm_id when creating or updating agents. |
Write Strong Extraction Fields
Use selector options for finite outcomes
Do not ask for free text when operations needs a clean report.
Use DateTime for schedulable callbacks
Ask for UTC ISO 8601 output when the caller gives a callback time, appointment time, or other follow-up date.
Extraction Problems
Field is empty
Field is empty
The transcript may not contain the fact, or the description may be too vague.
Selector returns unexpected value
Selector returns unexpected value
Use clearer allowed options and descriptions.
Boolean feels inconsistent
Boolean feels inconsistent
Define what counts as true and false.
Callback time cannot schedule a workflow
Callback time cannot schedule a workflow
Use the DateTime field type and describe the expected UTC ISO 8601 output. Workflow Time nodes should point at a DateTime PCA field.
