Call failures graph

The chart uses colored lines to help you visualize the trend of the failure reasons over the specified time interval. The number of failed calls is displayed on the vertical axis, while the time interval is shown on the horizontal axis. This representation is useful because it keeps you informed about the causes that did not allow the calls to be completed.

Call failures table

The table is dynamically generated, depending on your search criteria. All reasons for failure can be displayed:

• Day/Month: The day(s) or the month(s) the call failures are displayed for.
• Failed: The number of failed calls.
• Not answered: The number of calls unanswered by the callee.
• Busy: The number of unanswered calls because the called party was unavailable or involved in another call.
• Unknown: The number of calls that failed due to an unknown reason.
• Not allowed: The number of calls that failed because they were not allowed to reach their destinations.
• Total: The total number of call failures in a day/month.

No matter the failure reasons, the table will only display two columns:

• Day/Month: The day(s) or the month(s) the call failures are counted for. If you have chosen a time interval shorter or equal to a month, this column will display the Days. Otherwise, the Months will be shown.
• Calls: The number of failed calls in a day/month.

Search for statistics

If you want to view the Call Failures (CF) statistics for a specific period of time or for a certain failure reason, you can use the available search controls to define your preferences:

Where:

• <start_date_time>: Specify when the time interval for the current statistics starts. Mandatory format: yyyy-mm-dd hh:mm. Default value: the first day of the current month.
• <end_date_time>: Specify when the time interval for the current statistics ends. Mandatory format: yyyy-mm-dd hh:mm. Default value: the current date and time.
• <failure_reason>: Choose the cause of failure for the statistics.
  • All - Displays all daily/monthly call failures.
  • <failure_reason> - Displays the number of calls that failed due to a certain reason.

After deciding on the filters, click the Search link. The graphic and the table will be updated.

Export statistics

You can export the Call Failures data to a .csv or a Microsoft Excel file:

1. Click the Export icon in the upper right side of the screen.

2. Choose the columns to be exported and the output file format. If you choose to export the data to a Microsoft Excel file, the output will be a table with all selected columns. On the other hand, if you choose to export the data to a .csv file, the output will be a list with the entire selected information in the following format:

   <day> <failed> <not_answered> <busy> <unknown> <not_allowed> <total>

3. After defining all preferences, click the Save icon. You will be asked to confirm if you want to save the file to your computer or just open it.
