Call Failure Locations

Summary

I can see an overview of the proportion of setup to mid-call failures and how many of these have occurred each day.

I can see a breakdown of AD country / city / department, or building region / country / city and the number of failures for each, allowing easy identification of problem areas.

Setup failures are recorded when a call is attempted but can’t connect – for example an issue with a Direct Routing gateway.

Mid-call failures are recorded when a call starts successfully but drops – for example if Wi-Fi coverage is poor.

This report tells me

Summary

• Total number of calls
• Calls without failures – number and percentage
• Calls with failures (either) – number and percentage
• Calls with setup failures – number and percentage
• Calls with mid-call failures – number and percentage

Call setup & mid call failures

• Number and percentage of setup / mid-call failures

Call setup failures over time

• Number of call setup failures, one point per day

Mid call failures over time

• Number of mid call failures, one point per day

AD Countries with call setup failures

• Number of call setup failures, one bar per AD country

AD Cities with call setup failures

• Number of call setup failures, one bar per AD city

AD Departments with call setup failures

• Number of call setup failures, one bar per AD department

AD Countries with mid call failures

• Number of mid call failures, one bar per AD country

AD Cities with mid call failures

• Number of mid call failures, one bar per AD city

AD Departments with mid call failures

• Number of mid call failures, one bar per AD department

Tips

You can use highlighting in Power BI to quickly see an area of interest – for example clicking United Kingdom in “AD Countries with call setup failures” will filter the rest of the report so you only see UK cities/departments in the remaining visuals.
