Using the UCC Dashboard

The UCC dashboard in AirWave displays charts that show UCC trends to network administrators. Non-admin users can view information for the devices and folders to which they have access.

Viewing Call Details

You can view call details by clicking the Call Details link at the lower-left of each graph. Information, such as the operating system of the client device, protocol used to complete the call, and connectivity type are all displayed in the table view. From AOS 6.5.0.0 and 8.2.0.0 or later, you can also see who provides the UCC service for Wi-Fi calls.

You can look for any device issues that are detected during the call in the End-to-End Quality field, or network quality issues in the Mean Opinion Score (MOS) field. The MOS is updated after a call has ended.

By default, the data in this table is displayed by the call start time, with the most recent call at the top of the list.

To change how the data is displayed, do any of the following:

• Click the column heading to sort the data. 
• Click at the top of column headings to filter the data.
• Click the Show link to add parameters like Protocol to the table view.

Tips for Filtering Calls

If you want to reduce the amount of calls that appear as unknown, you can filter the results by call types. When you select Voice, the UCC dashboard shows only voice calls and conference calls. When you select Others, any other type of call, such as video and desktop sharing, is reported.

The UCC dashboard also displays calls based on the end-to-end call quality. When you select WLAN, information displayed is based on the UCC score of the calls.

Viewing UCC Charts, Graphs, and Tables

AirWave aggregates UCC call data and presents them in charts, graphs, and tables. Hovering over the charts displays details about the highlighted section of that chart.

Call Quality

Call quality is measured by a metric called the UCC score. This metric takes into account delay, jitter, and packet loss. AirWave obtains these metrics from RTCP messages sent from the client (if the client is capable of sending them). For audio calls, AirWave obtains these metrics from the HPE Aruba Networking AP that inspects the RTP flows.

The following table describes the UCC scores and quality indications.

Table 1: UCC Quality Levels

UCC Score	Quality Indication
71 or greater	Good quality seen by the network
31 to 70	Fair quality seen by the network
0 to 30	Poor quality seen by the network

To view call quality information, click the following hyperlinks:

• Trend—This chart shows the number of calls with good, fair, or poor client health over the selected time period.
• Distribution—This graph shows the relative proportions of calls with each quality type.
• APs—This chart shows information about APs that supported poor quality calls.
• Folder—This table view shows all folders that carried calls and, for each folder, the percentage of calls that were rated poorly by UCC.

Quality Correlation

These graphs display the correlation between call quality and client health. The client health metric displayed is the efficiency at which that AP transmits downstream traffic to a particular client. AirWave determines this value by comparing the amount of time the AP spends transmitting call data to a client to the amount of time that would be required under ideal conditions at the maximum Rx rate supported by client, without data retries.

For example, a client health metric of 100% means the actual airtime the AP spends transmitting data is equal to the ideal amount of time required to send data to the client. A client health metric of 50% means the AP is taking twice as long as is ideal, or is sending one extra transmission to that client for every packet. A metric of 25% means the AP is taking four times longer than the ideal transmission time, or is sending 3 extra transmissions to that client for every packet.

To view quality correlation information, click one of the following hyperlinks:

• Trend—This chart shows the number of calls with good, fair, or poor client health over the selected time period.
• Scatterplot—This chart shows a historical view of the call quality and client health of each individual call. To view call details for a specific client, click on a call session. For more information, see Viewing End-to-End Call Details.
• Connectivity—This table view shows the number of calls of each quality level (good, fair, poor, and unknown) by connectivity type (wired to Wi-Fi, wired to external, wired to wired, Wi-Fi conference, Wi-Fi to external, and Wi-Fi to Wi-Fi).

Call Volume

To view call volume information, click one of the following hyperlinks:

• Trend—This graph and table displays the number of calls made during the selected time period using a UCC application, such as SIP, Lync, and FaceTime.
• APs—This graph displays the names of the APs that supported these calls.

Devices

These graphs display information about the calls made by different device types, such as Windows 7, Mac OS X, iPhone, or Android devices.

• Trend—This graph show the numbers of calls by each platform type over the selected time period.
• Distribution—This chart shows the relative proportion of calls that originated form each device type.
• Quality—This graph shows the numbers of calls at each quality level made by each device type.

Viewing End-to-End Call Details

For an end-to-end view about a call, go to Home > UCC > Call Quality > Call Details and click the magnifying glass icon in the Details column. Overall client health is rated good, fair, or poor (see Quality Correlation for information about the UCC score).

Client information, such as a description of the client device, the signal-to-noise (SNR) ratio for the call on the client's connection, speaker and microphone glitch rate, and transaction rates, are provided in this table view.

Table 2: AP Details

Column Name	Description
AP Type	The type of AP to which the client is connected.
Radio Name	The AP's radio being used for the call (802.11bgn or 802.11ac)
Radio MAC	The AP radio's MAC address.
Concurrent Poor Calls	The number of poor calls occurring simultaneously with the call being viewed.
Channel	The channel used for the call.
Channel Utilization	The used channel's utilization as a percentage.
Channel Interference	The interference impacting the used channel as a percentage.

Get Call Summary

Use the Summary tab to see more call details and a graph displaying the quality of the call as it progressed. Hovering over the graph displays a snap-shot of the call at two-minute intervals, which can help you identify when changes occurred during the call.

Figure 1  Call Summary Information

To view more details about a call, click the More link at the lower right of the Summary tab.

• Microphone Details—This information about the client's microphone includes manufacturer and model, the capture device driver, glitch rate, and audio microphone error.
• WLAN—This information repeats some of that shown on the End-to-End tab, in addition to WLAN delay, jitter, and packet loss.
• End To End—This information, about the connection between the caller and receiver, includes MOS, delay, jitter, packet loss, and burst gap details.
• End Point Details—This information about the device used by the caller includes IP address, Wi-Fi device driver, CPU details, and OS.
• Speaker Details—This information describes the type of speaker used by the caller.

For a granular look at a specific call, click the Details tab. It shows the same information found on the Summary tab in table divided into two-minute intervals.

Using the UCC Report

The UCC report provides an overall look at UCC activity on your network in the specified time period. This information is displayed in a series of tables representing the top connectivity types, call types, application types, device types, folders, APs, and clients with the highest percentage of poor quality calls.

You can filter UCC reports by SSIDs as shown in Figure 2. To create a UCC report go to Reports > Definitions, then click Add.
