Understanding the Dashboard

The main dashboard gives an at-a-glance visualization of the usage of the system and the media quality experienced by a customer.

The bell notification icon showcases new feature releases available for the Calling Metrics dashboard and provides insight to “What’s New” and a link to the new feature documentation.

Note: Each new feature notification displays for 2 weeks.

Date Range

The Date Range option, located on the main landing page, allows a user to view through day, week or month of data, as needed.

The date range applies for the following graphs.

• Calls for all sites
• Call quality for sites
• Devices

Note: The date range applies only to the main dashboard landing page and does not apply to the “Total Calls” graph. This graph always shows data for the last 30 days.

Examples for date ranges

Choosing multiple days’ worth of data:

In this example, the start date is December 14, 2020 and the end date is December 17, 2020.

Resetting and choosing a different date range:

For choosing a different date range, move your mouse either over the start date or end date. Then click on the close” button to reset the current selection.

Call Quality

• The Poor Calls section shows the number of calls within your domain having MOS scores below 3.2 in the last 24 hours.
• The Good Calls section shows the number of calls within your domain having MOS scores above 3.8 in the last 24 hours.
• The Call Quality section identifies the top poor call sites in conjunction with a call quality breakdown. The call quality is provided in 3 categories within the last 24 hours for an individual site:
• Good (MOS > 3.8)
• Fair (MOS 3.2 to 3.8)
• Poor (MOS < 3.2)

Reading the Calling Metrics View

The Calling Metrics view displays a list of calls made during a given time period with complete call details. You can select a site and time period to view a list of calls and associated media quality information. Columns can be sorted to display calls in order of whichever metric is pertinent to the problem that is being worked.

Within the Customizable Column, the Additional Settings button allows a user to customize the column they want to view under the Call Metrics tab. This provides the ability to add or remove additional fields as well as organize and reorder columns.

To customize your column view, click on the “Additional Settings” tab and select the individual fields from the drop-down menu or click the “Select All” option.

Note: Only fields under the “Additional Settings” tab can be customized (ie, added or removed)
The fields listed below are set to default and cannot be removed.

• Start time
• Duration
• Calling Number
• Caller
• Called Number
• Callee
• Call Quality
• Packet loss (PL) %
• More Info

Example for customized view

For this example, a selection of fields are chosen for viewing under the Call Metrics tab: Call type, Jitter average callee, Packet loss caller and callee.

Download button

The download button for Call Detail Records (CDR) provides the ability to download the contents of CDR metadata. It offers insight on how a specific phone number and/or users are utilizing the phone system and helps to identify their calling trends.

By navigating to the Calling Metrics tab, you can choose any site and date then select the download button. This will download the CDR contents in excel file format.

Note: The downloaded file is not site specific and contains calling trends for all sites. Additionally, only a day worth of data can be downloaded.

Call Type

Call Type Column

The Call Type column in the Call Details list allows you to quickly identify what type of call a particular record is associated with. It is important to note that the only records that are shown on the Call Metrics Dashboard are those that had a media session. The dashboard, by design, does not show unanswered calls. A complete view of call history can be seen under the Analytics tab in the Calling Admin Portal.

Call Type Examples:

1. Call Transfer:
   

   Click image for large view
   • At 09:34 PM, Alice called Bob (+14307973003 -> +14307973004), Call duration 223 seconds.
   • Bob initiated a call transfer to Carol.
   • At 09:36 PM, Alice and Carol were in conversation (+14307973003 -> +14307973005).
   • The dashboard lists two calls because there were two media sessions. First call would be Alice to Bob (09:34 PM) and the second call would be Alice to Carol (09:36 PM).
   • The “Call Type Column” Indicates that this is a “Call Transfer” scenario.
   • The “redirecting number” explains who attempted the transfer. In this case, it would be Bob’s number (+14307973004).
   • The “reason” explains that there was a “deflection” during a course of the call which indicates call transfer.
2. Hunt Group:

Click image for large view
• At 10:27 PM, Dave called a Hunt Group number.
• Alice is an agent on this Hunt Group, and she attended the call.
• Dave and Alice spoke for 121 seconds (+14307973002 To +14307973003).
• The dashboard lists one call as the call had one media session. I.e., Dave (caller) to Alice(callee) at 10:27 PM.
• The “Call Type Column” indicates that this is a “Hunt Group” scenario.
• The “redirecting number” denotes the actual “hunt group” number (+14307973009) which then forked the other agent phone number.

Call Quality and Packet Loss (PL%) Columns

The Call Quality and PL % columns in the Call metrics tab list allow you to quickly identify media quality problems for a particular call.

Packet Loss Example:

• Alice called Bob
• Alice’s media stream to Bob experienced 2% packet loss
• Bob’s media stream to Alice experienced 8% packet loss
• he PL% columbine the dashboard lists the worst of these two values, in this case 8%

Below is a simple example to demonstrate troubleshooting media quality issues using the Calling Metrics dashboard.

• The dashboard shows a site where poor quality has been measured. Clicking on the “poor calls” takes you to that site immediately.

In the example below:

• The poor calls were clustered during office hours, from 10:42am to 11:09am and were mostly between Alice and Bob.
• Alice’s phone number is +14307973003 and Bob’s phone number is +14307973004.
• For each of the 5 calls listed, the PL% column shows consistent packet loss ranging from 5-8% and, as a result, the call quality was poor.

To troubleshoot further, choose a particular call, click on the More Info column, as shown in the below image, and choose the Call stream metrics graph. This will show the trend of media packets flowing between both Alice and Bob.

• The “X” axis is the call duration and the “Y” axis is the Packet Loss %.
• There are two datasets on the graph, in the below example. The gray line represents media packets flowing from Alice to Bob (+14307973003 to +14307973004).
• The blue line represents the media packets from Bob to Alice (+14307973004 to +14307973003).
• For this call example, it is clear that the media flow from Bob to Alice had issues indicating a potential issue on Bob’s end.
• This would point to there being a problem with the network on Bob’s end, which would require further investigation.

On the Call Details page, the SIP call flow section shows the requests and responses made by the caller and callee for the selected call. Only SIP signalling between the endpoint and the access side SBC are shown.

Select the Call Stream Metrics column to show the Packet Loss over time, if it’s available for a particular call.

Data Retention

Data retention for the Calling Metrics Dashboard is 30 days for general call and media quality data. SIP signalling and Call Stream data is available for 7 days.

Troubleshooting Examples

These examples are common media quality issues and how you would investigate them using the calling metrics dashboard. With these tips, you can quickly narrow down an issue.

Example 1: A single user reports poor media quality

If a single user reports poor media quality, use the service assurance dashboard to do the following:

• Check the user’s site on the dashboard, and by looking at individual call records, determine if all users are experiencing problems?
• If other users are also seeing issues, use the filtering tools to view past calls to see when this issue began and troubleshoot the sites network connectivity, using Examinet or other tools.
• If other users are not seeing issues, filter/sort the calls to view that user’s calls only.
• From this list, it should be clear if there is a pattern to their calling issues:
• All calls from a particular device have issues, but calls from other devices are ok.
• Troubleshoot that single device.
• Only calls at busy periods are showing issues.
• This points to bandwidth contention during busy periods.
• Other users using a particular device type are also having issues.
• These devices may be having issues on the customer’s network.

Example 2: A single site shows bad media quality in the admin portal

The calling metrics dashboard can isolate a list of calls for a particular site by filtering on the Call Details page.

• From this list, problem calls can be sorted and the following patterns identified to isolate the problem.
• Are the problem calls coming from the same user?
• Are the problem calls happening every day at the same time?
• Are the problem calls specific to a device type?

Example 3: An entire customer reports bad media quality

• Is the issue across a single site or multiple sites?
• If it is across a single site, there are no issues with the cloud service, and that sites connectivity should be investigated.
• If it is across multiple sites, are other customers also having issues? The BroadCloud Status page should list any active issues with the overall service.

If there are no service issues, the site network connection should be investigated using Examinet or other tooling.
