Directory lookup not working – Unified Attendant Console Standard V11.0.2.

In some cases when you complete the installation of the Attendant Console Standard, you may notice that the Directory lookup is not working. You may ask yourself, what could be the issue.

The issue

Plain and simple, the Attendant console is not able to return any information from the Directory
