You must purchase the wallboard separately, and configure and control it with its own wallboard software. Wallboard software and hardware are supported by the third-party wallboard vendors, not by Cisco.
You must install the wallboard software on a separate machine or desktop, not on the Unified CCX server. During installation of your wallboard software, you will need to configure your wallboard software to access the Unified CCX database. To do this, you need to assign a DSN, User ID, and password.
