Customer Wallboard not displaying, then maybe an issue after a reinstall, or upgrade.
Firewall Settings: If the server is running a firewall then traffic on some additional ports may need to be allowed.
Port Description
• TCP 80 User browser access to IP Office Customer Call Reporter.
• TCP 1433 IP Office Customer Call Reporter to SQL access.
• UDP 1434
• TCP 8135 Wallboard access.
The details here cover the addition of those ports for the default Windows firewall.
1. Access the Widows Firewall settings (Start | Control Panel | Windows Firewall).
2. Select the Exceptions tab.
3. Click Add Port....
4. Enter a name to describe the function, for example IPOCCR SQL Access. Set the Port to 1433 and TCP.
5. Repeat the above operation for the other ports required.
This has worked for me.
6. Click OK
