13.8.1 Configuring Quality of Experience per Media Realm

You can configure Quality of Experience (QoE) per Media Realm. This enables you to
monitor and analyze media and signaling traffic, allowing you to detect problems causing
service degradation. The device can save call information and statistics at call start, at call
end, or at specific changes in the call. The information is stored as call records on an
external server. The device connects, as a client, to the server using TLS over TCP.
You can specify the call parameters to monitor and configure their upper and lower
thresholds. If these thresholds are exceeded, the device can be configured to do the
following:

Reports the change in the monitored parameter to the monitoring server (default).

Sends RFC 2198 RTP redundancy packets on the call leg that crossed the threshold.
This enables the device to adapt to the changed network status. In this option, you
can also configure the redundancy depth. The channel configuration is unchanged if
the change requires channel reopening. Currently, this option is applicable only when
the monitored parameter is remote packet loss.
The device can be configured to monitor the following parameters on the local (i.e., at the
device) or remote side:

Packet loss

Mean Opinion Score (MOS)

Jitter

ranges or all without; not some with and some without.

The available UDP port range is calculated using the
BaseUDPport parameter:

BaseUDPport to BaseUDPport + 255*10

Port ranges over 60,000 must not be used.
Defines the number of media sessions associated with the
range of ports. This is the number of media sessions
available in the port range. For example, 100 ports
correspond to 10 media sessions, since ports are allocated in
chunks of 10.
Read-only field displaying the ending port for the range of
Media interface UDP ports. This field is calculated by adding
the 'Media Session Leg' field (multiplied by the port chunk
size) to the 'Port Range Start' field. A value appears once a
row has been successfully added to the table.
Defines the Media Realm as the default Media Realm. This
default Media Realm is used when no Media Realm is
configured for an IP Group or SRD for a specific call.

[0] No (default)

[1] Yes
Notes:

This parameter can be set to Yes for only one defined
Media Realm.

If this parameter is not configured, then the first Media
Realm in the table is used as the default.

If the table is not configured, then the default Media
Realm includes all the configured media interfaces.
