Configuring QoE Thresholds

QoE Thresholds determine global (system-wide) voice quality thresholds templates. Four QoE Thresholds templates (Low Sensitivity | Medium Sensitivity | High Sensitivity | MS Teams) monitor the voice quality metrics of MOS, Delay, Packet Loss, Echo and Jitter can be configured. Microsoft Teams Video thresholds can also be configured. Based on the values determined for these metrics, the call quality is graded as Poor', 'Fair' or 'Good'.

When you add a new tenant, the defined templates are automatically added as profiles. In the example shown below, all four of the above-mentioned templates are automatically added as profiles to the new tenant 'SBC Test'. You can then customize these profiles according to customer requirements (see Configuring QoE Threshold Profiles).

➢

To add QoE thresholds templates:

1.

Access the Global scope (see Accessing Scopes).

2.

From the System menu, open the QoE Thresholds page (System > Configuration > Templates > QoE Thresholds).

3.

Click Add to add a new QOE threshold.

Use the following table as reference to the figure above.

Template	Description
Low Sensitivity Threshold	Threshold values representing recommended data for the 'Low' sensitivity level.
Medium Sensitivity Threshold	Threshold values representing recommended data for the 'Medium' sensitivity level.
High Sensitivity Threshold	Threshold values representing recommended data for the 'High' sensitivity level.
MS Teams Threshold	Threshold values representing recommended data for the 'MS Teams' threshold. For Teams devices, AudioCodes recommends you use the Microsoft Teams threshold. It's a threshold that is added by default to each tenant. It enables calculating the quality of Teams calls.

4.

Provide an intuitive name for the profile. As a reference, use the names of the four QoE Threshold Templates displayed in the table above.

5.

Enter a description of the profile to facilitate effective intuitive management later.

6.

Select the Device option to set the profile as default.

7.

Select the SIP Connection option to set the profile as default.

8.

Select the Endpoint option to set the profile as default.

9.

By default, All metrics are included in the profile, except for Teams where the metric Echo is excluded. To exclude a metric, clear its check box. To define the MOS metric, for example, click the bar or drag the markers. Each bar unit increments or decreases the threshold by 0.1 (MOS, Packet Loss), or by 1 (Delay, Jitter, Echo).

10.

Do the same for the other metrics thresholds.

11.

In the QoE Thresholds Details screen for the Microsoft Teams profile, click the Video tab (the settings described in the preceding steps were related to the Voice tab).

Use the following table as reference to the preceding figure.

QoE Thresholds Details - MS Teams Thresholds - Video

Setting	Description
Avg Video Frame Loss Percentage (%)	Threshold values representing recommended data for the 'Low' sensitivity level.
Avg Video Frame Rate (fps)	Threshold values representing recommended data for the 'Medium' sensitivity level.
Post Forward Error Correction Packet Loss Rate	Threshold values representing recommended data for the 'High' sensitivity level.
Screen Sharing
Avg Video Frame Loss Percentage (%)	Same as for video. Threshold values representing recommended data for the 'Low' sensitivity level.
Avg Video Frame Rate (fps)	Same as for video. Threshold values representing recommended data for the 'Medium' sensitivity level.
Post Forward Error Correction Packet Loss Rate	Same as for video. Threshold values representing recommended data for the 'High' sensitivity level.

12.

Click OK; the profile is displayed in the QoE Thresholds screen.

➢

To edit a QoE Threshold:

1.

Select the check box adjacent to the desired QoE threshold, and then click Edit.

2.

Configure parameters according to the table above.

You can view a snapshot of the QoE Thresholds details in the Details pane when selecting the entry.

➢

To delete a QoE Threshold:

1.

Select the check box adjacent to the desired QoE threshold, and then click Delete.
