Network Testing Companion User Guide
To start the Skype for Business and Microsoft Teams Network Testing Companion, select the icon on the desktop or on the Start menu. The companion first performs four checks to validate that the system is capable of performing an audio quality and connectivity test.
Note that this companion tests from the perspective of a client PC segment of the network. There are different Network Performance Requirements for the Client PC Segment VS the Edge Segment. This companion only compares against the Client PC Segment. For more information, please look at the network and performance requirements.
The following four areas are checked each time the companion starts up.
Note: You must have a local Administrator account to install or upgrade the Skype for Business Network Assessment Tool on a Windows PC.
Run network connectivity and quality tests
When you select the Start button in the test pane, the companion performs a connectivity check against the Microsoft Transport Relay network, making sure all the IP addresses and required ports are reachable. If any single IP address or port is unreachable, the test is considered to have failed and a red X is displayed under Connectivity on the Start tests tab in the test pane; if the connectivity test passes, a green check mark is displayed.
After the connectivity test, the companion runs audio quality tests. By default, it runs one test, which should take about 30 seconds from start to finish. You can configure multiple audio quality tests to be run and specify the interval between them; see “Configure test settings” later in this User Guide.
If all audio quality tests results are within limits, a green check mark is displayed under Quality on the Start tests tab in the test pane. If any of the tests fail, a red X is displayed.
View test results
You can get detailed reports about the connectivity and quality test results on the View results tab:
For detailed information about what these tests measure and how to interpret the results, see the Network Testing Companion Results Guide.
Configure test settings
You can choose the number of audio tests to run from the Consecutive audio tests list . From the Delay between audio tests (seconds) list, you can choose the amount of time (in seconds) to wait between each audio test. The Connectivity test timeout (seconds) controls after how many seconds a connectivity test should be considered failed.
An example of why you might want to modify the time between each test is when you’ve detected an audio issue that occurs at a regular interval (for example, lunch hour). By modifying the number of tests and time between each test, you can vary the total time it takes to run all tests from 1 minute to more than 30 minutes, and thus increase your chance of replicating and analyzing the issue.
The Network Testing Companion runs as a PowerShell module installed on your computer. You can easily remove it or update it manually by using the PowerShell Uninstall-Module and Update-Module cmdlets as an administrator. If you encounter an issue with the current version of this companion and you've installed a previous version, use the Uninstall-Module cmdlet to remove the most recent version.
