7.7 Running a VoIP Quality Assessment

In the Run view, start the VoIP Quality assessment by clicking Activate Assessment.

The status and the preliminary results are continually updated and indicate how the assessment is proceeding. Large assessments—that is, assessments with many call groups that are collecting timing records—take longer to process than smaller ones. When an assessment collects many timing records, even after all calls have completed, the Running indicator may still be spinning and the Status may still read “Calls running...” until results have been processed and entered into the database.

Field	Description
Status	The current status of the assessment. The assessment is ready to run when the status reads “Verified.”
Start time	The time you started the assessment.
End time (estimated)	The time you have scheduled the assessment to end. The end time is “estimated” because the run interval and call duration you specified, plus the time needed for the endpoints to report results, cannot be exactly calculated. The actual end time is set when the assessment is stopped or completed.
View Error Log	Accesses the Log Viewer, which lets you sort and filter errors and analyze their causes. For more information, see Section 11.3, Scheduler Errors.
View summary of most recent calls	Shows quality results only for the last set of simulated calls sent during the assessment.
View summary of all calls	Shows quality results for all simulated calls sent during the assessment.
VoIP tab	Contains the “Call Groups—MOS Summary of All Calls” table, a table of preliminary results for each call group: Errors—Indicates whether any errors occurred during calls run between the endpoints in this call group. Endpoint 1—The computer acting as Endpoint 1 in the call group. Initiates the calls and reports results back to the database. Endpoint 2—The computer acting as Endpoint 2 in the call group. Script—The script used. Generally refers to the codec, but some optional parameters can be altered. For more information, see Section 7.11.2, Reviewing Codec Types. # Concurrent Calls—The number of concurrent voice over IP calls represented by the connector of the current call group. Total Calls Simulated—The number of simulated VoIP calls sent over the network between the endpoints in the call group. %Good, %Acceptable, %Poor—Percentage of calls whose quality scores fell into the range of scores considered “good,” “acceptable,” or “poor” performance.
Background Traffic tab	Contains the “Background Traffic—Summary” table, which presents the configured and actual data rates for each call group.
Analyze and Chart Results button	Click to review the results of your assessment in Vivinet Assessor Analysis Console. For more information, see Section 9.0, Working with Analysis Console.

If an error occurs, click View Error Log to find out what happened. At any time, you can stop the assessment and change configuration parameters before starting it again. Simply click the Stop Assessment button.

Although the Run view lets you stop an assessment, the Vivinet Assessor Scheduler component will also stop the assessment when the time period you entered in the Schedule view has passed.

NOTE:

You can run an assessment of VoIP Quality and monitor Utilization at the same time. However, you must complete all configuration of each assessment type before you start either one. Once any assessment is active, no configuration options are available.
When you run an assessment again, all results from a previous assessment run are removed from the database.
