Cisco Cisco Unified CallConnector for Microsoft Windows

This section describes possibly unexpected behavior and describes only severity 1 and 3 caveats. 
Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious. Severity 3 caveats are 
moderate caveats.

This section contains the following topics:

Cisco Unified CME Version 4.3 is not supported

Cisco UCC Server and UCC Clients 1.4.0 are not compatible with Cisco Unified 
Communication Manager Express Version 4.3

VMWare is not supported

Cisco UCC Server and UCC Clients 1.4.0 do not support the VMWare virtual machine 
environments.

NAT is not supported

You cannot use Cisco UCC with a router that is running Network Address Translation (NAT). NAT 
routers do not forward packets between the Cisco UCC client and server.

The Activation check fails and asks to re-activate the license.

Both the Cisco UCC server and Cisco UCC clients have to be registered through an activation 
process before they can be used. This process sends the serial number and machine information to 
a License server and saves an activation record on the local computer. Every time the applications 
are run, this activation record is checked to verify the license.

In some situations, sometimes after a PC is re-booted or if the network adapters are disabled, then 
this activation check fails even though the a valid license is installed on the PC. This failure has also 
shown up on PC with Microsoft Windows Virtual Machines or virtual adapters.

As a workaround, you can enable the network adapter and re-start the Cisco UCC application or 
from the Popup About dialog clear and re-apply the serial number and activate the license again.

Co-existence issue with Skystone (stonevoice) Gateway; Related issues have been found with Office 
Communication Server. Overlap with Cisco UCC Server ports. 

As a workaround, need to install these components on another machine.
