How can I show a Dashboard for unknown callers?

No Dashboard is shown for unknown callers, because there doesn't exist a contact for the caller in the data sources of the Directory. How can I still show a Dashboard for unknown callers?

Two steps are necessary:

1) Navigate to the Connect Client settings of your location in the XPhone Connect server web interface. Scroll down to the "Advanced settings" and click on "Add...".

Add the following entry:

Name | Value
Dashboard.ForceEmptySearch | true

Save the entry and the Connect Client settings.

2) In the Dashboard Designer navigate to the desired Dashboard to be displayed for unknown callers.

In the area "Create/Edit Dashboard" choose the data source "Any data source". (You maybe need to click on the [...] button to find it.)

Save your Dashboard.

Unknown callers should now have a Dashboard displayed.
