Gateway Device Reports CAR provides reporting capabilities for three levels of users: administrators, managers, and individual users. Only administrators generate device reports. Device reports track the load and performance of Unified Communications Manager related devices, such as conference bridges, voice-messaging servers, and gateways. Only CAR administrators generate the gateway reports. The following sections describe how to configure Gateway Detail, Gateway Summary, and Gateway Utilization reports. Generate Gateway Detail Reports Only CAR administrators generate the Gateway Detail report. Use the Gateway Detail report to track issues with specific gateways. This section describes how to generate, view, or mail detailed information about selected gateways. Procedure Step 1 Choose Device Reports > Gateway > Detail. The Gateway Detail window appears. Step 2 To display the list of gateways that you can include in the report, in the List of Gateways box perform one of the following tasks: a) To display all gateways in the List of Gateways box, click Gateway Types in the column on the left side of the window.
