12.11 Configuring Quality of Experience Parameters per
Media Realm
For each Media Realm, you can configure Quality of Experience (QoE). The QoE feature
enables you to monitor and analyze media and signaling traffic, allowing you to detect
problems causing service degradation. The device saves call information and statistics at
call start, call end, or specific changes in the call. The information is stored as call records
on an external server. The device connects to the server using TLS over TCP (as a client).
For each Media Realm you can specify the call parameters to monitor and configure the
upper and lower thresholds, that when exceeded, the device reports the changes in these
parameters to the monitoring server. The device can monitor the following parameters:
Loss
MOS
Jitter
Delay
