Creating and Assigning Call Quality Thresholds › Assign a Call Quality Threshold

Assign a Call Quality Threshold

VoIP and video call performance occurs between pairs of related endpoints. Therefore, you want to understand the call quality data that is reported for paired network locations. By default, the Default call quality threshold is assigned to all pairs of Locations and media devices. In addition, you can assign custom call quality thresholds to selected pairs of Locations and media devices:

• Pairs of Locations to include all computers in the relevant Location subnets
• Pairs of media devices
• Pairs that consist of a Location and a media device

You can assign the same call quality thresholds to multiple pairs, such as all Locations in one geographical region of your enterprise. You cannot assign call quality thresholds to CA Performance Center groups.

Follow these steps:

1. Click Administration, Policies, Call Performance, Call Quality Threshold Assignments in the navigation bar.

   The Call Quality Threshold Assignment List opens.

2. Click New.

   The Call Quality Threshold Assignment Properties page opens. The Available Locations/Media Device Pairs list displays all Locations and media devices that have not been assigned to a threshold.

3. Select the threshold that you want to assign from the Threshold field.
4. (Optional) Select IP Domain if you are monitoring an environment with multiple custom IP domains.

   The Available Locations/Media Device Pairs list is filtered to show only pairs of Locations and media devices from the selected domain.

5. Select an item in the Available Locations/Media Device Pairs list.

   The Filter field accepts wildcard (*) search strings to limit the data in the list. For a string with no asterisks, the “Filter” field assumes wildcards (for example, “*abc*”) when it searches. Filtering can be useful when you have a long list of Locations and media devices.

   For example, to see only items for the Raleigh office, enter ral* for the filter and click Apply. Only items whose name begins with Ral are shown in the list.

6. Double-click the item in the Available list to move it to the Selected Location/Media Device Pairs list.

   Tip: You can use the Shift or Control key or click and drag with the left mouse button to select multiple items. Then click the Right arrow to move the items to the Selected list.

7. Save the assignment.
   • Click Save to save the assignment and return to the Call Quality Threshold Assignment List. The new assignment appears in the list.
   • Click Save and Add Another to save the assignment and remain on the Call Quality Threshold Assignment Properties page to assign another threshold.

   The threshold is now applied to the Locations and media devices you selected.
