User's Manual
Quality of Experience Profiles lets you define quality thresholds per monitored voice metric.
These are based on the following color-coded quality thresholds:
Green-Yellow threshold: Lower threshold that indicates changes from Green to
Yellow or vice versa when the threshold is crossed.
Yellow-Red threshold: Higher threshold that indicates changes from Yellow to Red
or vice versa when the threshold is crossed.
Hysteresis is also used to configure the threshold. This defines the amount of fluctuation
from a threshold in order for the threshold to be considered as crossed (i.e., change in
color state). Hysteresis is used to avoid false reports being sent by the device.
Each time a configured voice metric threshold is crossed (i.e., color changes), the device
can do the following, depending on configuration:
Report the change in the measured metrics to AudioCodes' Session Experience
Manager (SEM) server. The SEM displays this call quality status for the associated
SEM link (IP Group, Media Realm, or Remote Media Subnet). For configuring the
SEM server's address, see ''Configuring SEM Server'' on page 239.
Determine access control and media enhancements based on measured metrics.
Depending on the crossed threshold type, you can configure the device to accept or
reject calls, or use an alternative IP Profile for the IP Group to which the call belongs.
For more information, see ''Configuring Media Enhancement Profiles'' on page 247.
Alternative routing based on measured metrics. If a call is rejected because of a
crossed threshold, the device generates a SIP 806 response. You can configure this
SIP response code as a reason for alternative routing (see ''Configuring SIP
Response Codes for Alternative Routing Reasons'' on page 538).
Note:
Experience Profiles. One of these pre-configured profiles is the default Quality of
Experience Profile. Therefore, if you do not configure a Quality of Experience Profile,
this default is used.
The following procedure describes how to configure Quality of Experience Profiles in the
Web interface. You can also configure Quality of Experience Profiles using other
management platforms:
Quality of Experience Profile table: Table ini file parameter, QoEProfile or CLI
command, configure voip/qoe qoe-profile
Quality of Experience Color Rules table: Table ini file parameter, QOEColorRules
or CLI command, configure voip/qoe qoe-profile qoe-color-rules
To configure a QoE Profile:
1.
Open the Quality of Experience Profile page (Configuration tab > VoIP menu >
Quality of Experience > Quality of Experience Profile).
2.
Click Add; the following dialog box appears:
