Hi Rishikul,
Go to https://localhost/Prognosis/Admin/
Select Add System
Select in the "Cisco UCM Cluster" on the drop down menu in the PBXs section and click Add
Start adding the Display name, IP Address, Customer Name and Site Name. You will need a Username and Password with a particular mode and port Prognosis needs to access the CUCM.
You will need to configure CUCM too
