# Queue Callback Summary Report
The Queue Callback Summary report gives you a fast read on callback activity across your queues: how many callers requested a callback, how many of those callbacks connected, and how many failed. This page shows how to open the report and explains what each metric measures.
:::note
A queue callback lets a caller who is waiting in a queue hang up while keeping their place in line. When an agent becomes free, the system rings the caller back instead of making them wait on hold. This report tells you how well that feature is performing for each queue.
:::
## Open the Queue Callback Summary report
1. Sign in to the PBX web portal and go to **Reports and Recordings > Call Reports**.
2. Open the **Default Reports** tab.
:::note
Cloud Voice rebuilt the CDR (Call Detail Record, the log the system keeps for every call) module in version **84.21.0.117**, introducing a new data structure that shows call details more clearly and in more depth. Older CDRs and the report data tied to them are removed over time according to your **CDR Auto Cleanup** setting. Until that cleanup finishes, the old and new records live under separate tabs: **Default Reports** holds records created on the new structure, while **Call Reports (Legacy)** keeps the historical records. The steps here cover the new data on the **Default Reports** tab. To review data generated before the upgrade, open the **Call Reports (Legacy)** tab instead.
:::
3. In the **Call Center Reports** pane, select **Queue Callback Summary**.
4. Set the report filters:
a. In the **Time** field, choose the date range the report should cover.
b. In the **Queue** drop-down, pick one or more queues to include.
The report matching your filters appears on the page.
