Being asked if it is possible to remove devices showing up in a Dashboard for MOS metric data that do not have voice configured.
A View is configured to show metric data in Ascending order. This shows the lowest values, the worst values, first.
There are devices that are discovered which support these metrics, MOS tests in this instance, but the device is disabled for these tests. As a result it's expected to see zero values for the related metrics.
When the View shows items in Ascending order, it lists those with the expected zero values first. This moves devices with real data, those with low values that require further review, below the zero values. They are somewhat hidden at first glance.
The View is using All Groups. This will provide all devices that support the Views metrics.

There are two ways to resolve this.
