11.2 VoIP Quality Assessment Errors

Certain types of errors that occur during a VoIP Quality assessment are no real cause for concern. For example, Vivinet Assessor may detect an error in one of the endpoint computers’ high-precision timers and generate error CHR0359. If you see this error while the assessment is running, there is no need to stop the assessment because the error will not invalidate your results. If you see the error during verification, simply run the verification again.

A lack of endpoint availability is a common source of errors and can occur if network links go down, if the endpoint software is improperly installed, or if the software or the computer where it is installed is no longer running.

Other types of errors that commonly occur will invalidate or impede the VoIP Quality assessment. When one of the endpoints is powered off during the assessment period, your results will show CHR0200. A few examples of this problem over the course of a seven-day assessment will not invalidate the assessment, but obviously, as long as the target computer is inactive, you are not logging any results for that call group. If you see error CHR0125 while an assessment is running, you should stop the assessment. An endpoint you included in the Design is an older endpoint version and does not support VoIP Quality assessments. Take one of the following steps:

  • From the table in the Run view, right-click over the call group that shows the error and select Show Connector in Design to jump to that endpoint. Change the Design to exclude it.

  • Install the latest version of the endpoint software on the affected computer.

When you receive an error, you should always check the Log Viewer and read the error details, which provide detailed Help for each error message. Click View Error Log to find out more about the error. For more information, see Section 11.5, The Log Viewer.
