## Before you start

- An AI agent that has already answered, even a test call: see [Create and test your AI receptionist](https://callizy.ca/en/apprendre/creer-sa-receptionniste).

## Step by step

6 steps, about 4 min.

Screenshots show Callizy in French. Button names are given in English.

### 1. Open the call history (10 s)

In **AI voice agents**, on the agent’s card, click the three dots, then **Call history**.

Menu: Administration › AI voice agents › your agent › Call history

### 2. Find a call (30 s)

On the left, the **Conversations**, the most recent at the top. **Search a conversation…** searches the number, the contact’s name, the summary and the transcript.

### 3. Listen to it (1 min)

Click a call. The player plays the recording. The **10s** buttons go back or forward 10 seconds.

### 4. Read the summary and the transcript (1 min)

**Overview** tab: the **Duration**, the **Summary** and the **Call details**, with the number, the direction, the date and the time. **Transcript** tab: the conversation, turn by turn, **AI Agent** and **Client**.

### 5. Open the change history (20 s)

Open the agent with the pencil. At the top, click the clock, to the left of **Test**: **Change history**. Each line says what changed, when, from where (**in the dashboard**, **via the API** or **undo**) and by whom.

### 6. Go back (30 s)

Click a line: **Before** and **After**, field by field. **Go back to before this change** puts those fields back. “Agent put back to its previous state.” confirms it.

## Key points

- Test calls are in the call history too.
- The change history keeps the last 100 changes.
- Going back only touches the fields of that change. It is a change itself: you can undo it.
- Going back never deletes an added knowledge page: it turns it off.

## Not working?

### Callizy shows “No conversation”

1. The agent has not received a call yet. Make a test call with **Test**, then **Call me**.

### Callizy shows “No audio recording”

1. This call has no audio. Read its **Summary** and its **Transcript**.

### Callizy shows “Could not go back.”

1. Reload the page, then try again.

## Frequently asked questions

### What does the change history track?

The name, the greeting, the instructions, the context, the language, the voice, the active state, the texts, the transfers, the notifications, the knowledge, the web pages and the reference tables. Missions and the calendar are not in it.

### Are changes made through the API or Claude tracked?

Yes. They show **via the API**, with the name of the key.

### Where can I see all calls, not just the agent’s?

See [Find a call: history, recording, AI summary](https://callizy.ca/en/apprendre/retrouver-un-appel).
