# Call Topics

> Define the topics used to classify completed calls.

Call topics classify what a completed conversation was about. Use them to organize Call History and compare common reasons for calls in Performance.

## Define topics

Open the agent's **Settings**, select **Call Tagging**, and add each topic with a name and description.

* Use the **name** as the stable reporting label.
* Use the **description** to explain when the topic applies.
* Keep topics distinct enough that the same conversation is not routinely ambiguous.

For example, prefer separate topics such as `New appointment`, `Reschedule appointment`, and `Cancel appointment` when those categories lead to different operational decisions.

Phonely analyzes completed calls against the agent's configured topics. A call can contain more than one topic.

## Review and use topics

Topics appear in [Call History](/call-history-ai-analytics/call-history-ai-analytics), [Call Details](/call-history-ai-analytics/call-history-ai-analytics#review-call-details), [Performance](/performance) filters and charts, and [Data Tables](/data-tables). In a completed call's **Highlights**, you can add or remove topics when the classification needs correction.

When you rename or remove a configured topic, earlier calls can still contain the previous value. Review saved Performance and Data Table views that refer to it.

<Tip>
  Topics describe what the call was about. Use [Call Outcome Tagging](/blocks/common-settings#call-outcome-tagging) for a result recorded by the flow, and [Post-Call Outcomes](/post-call-outcomes) for a result added later through the API.
