# Extension Call Accounting Details Report

The Extension Call Accounting Details report itemizes the charge for each outbound call an extension makes over a given trunk (the connection that carries calls to and from the phone network). Use it when you need line-by-line billing detail rather than a summary. This page explains how to open the report and what each figure represents.

:::tip
Reviewing this report on a regular schedule, or having it emailed to you automatically, helps you spot unusually expensive or unexpected calls early. A sudden jump in cost is a common early sign of toll fraud or misused resources.
:::

## Prerequisites

At least one [call rate rule](/pbx/administrator-guide/add-a-call-rate-rule/) must already be in place, since the report prices calls against the rates you define.

:::caution
The **Amount** column is calculated from your call rate rules. If an outbound route or trunk has no matching rule, its calls cannot be costed, so confirm your rules cover every route you want to bill before you rely on the totals here.
:::

## Open the report

1. Sign in to the PBX (Private Branch Exchange, your phone system) web portal and go to **Reports and Recordings > Call Reports**.
2. Open the **Default Reports** tab.

   :::note
   From Cloud Voice firmware `84.21.0.117` onward, the CDR (Call Detail Record) module stores call data in a redesigned structure that presents details more clearly. Earlier CDRs and the report data built from them are purged gradually according to your **CDR Auto Cleanup** setting. While both sets coexist, they are kept apart: newer data appears on the **Default Reports** tab, and pre-upgrade data on the **Call Reports (Legacy)** tab.

   The instructions here apply to data recorded on `84.21.0.117` or later. To review data from before the upgrade, work from the **Call Reports (Legacy)** tab instead.
   :::
3. In the **Accounting Reports** pane, select **Extension Call Accounting Details**.
4. Define what the report should include.
