14.8 Quality of Experience
This chapter describes how to configure the Quality of Experience feature.
14.8.1 Reporting Voice Quality of Experience to SEM
The device can be configured to report voice (media) Quality of Experience (QoE) to
AudioCodes' Session Experience Manager (SEM) server, a plug-in for AudioCodes EMS.
The reports include real-time metrics of the quality of the actual call experience, which are
then processed by the SEM.
SEM is a VoIP-quality monitoring and analysis tool. SEM provides comprehensive details
on voice traffic quality, allowing system administrators to quickly identify, fix and prevent
issues that could affect the voice calling experience in enterprise and service provider VoIP
networks. IT managers and administrators can employ SEM in their VoIP networks to
guarantee effective utilization, smooth performance, reliable QoS levels, and SLA
fulfillment.
Note: For information on the SEM server, refer to the SEM User's Manual .
14.8.1.1 Configuring the SEM Server
The device can report QoE voice metrics to AudioCodes SEM server.
You can also configure at what stage of the call the device must send the report to the
SEM server. The report can be sent during the call or only at the end of the call. Reporting
at the end of the call may be beneficial when network congestion occurs, as this reduces
bandwidth usage over time.
Notes:
•
To support this feature, the device must be installed with the relevant Software
License Key.
•
To configure the parameters to report and their thresholds per Media Realm, see
'Configuring Quality of Experience per Media Realm' on page
