Hi Matthew,

You would need to install this Device Package to your existing 4.1(3) build to add support for these new IP Phone models;

Cisco Unified CallManager Device Package 4.1(78.0)

Release Notes

Procedure

NOTE: Apply this patch to all of your Cisco CallManager servers, beginning with the publisher server and TFTP server.

When applying this Device Package to enable new device support, a cluster-wide reboot is required for those devices to register successfully. A clusterwide reboot IS NOT required when running to update existing firmware/support.

If installing on a Cisco Unified CallManager version earlier than 4.1(3)sr2, the following message will be displayed: “Install on all nodes is required. All nodes will be rebooted as part of the installation.”

If installing on Cisco Unified CallManager 4.1(3)sr2 (recommended), the following message will be displayed: "Install on Publisher and TFTP server is required. Installation on all nodes is highly recommended." A clusterwide install/reboot is required.

Perform the following procedure to install Cisco Unified CallManager Device Package X.X.exe:

1. Download the ciscocm-4-1-DevPack-X.X.exe file to your hard drive. Make a note of the location where you saved the file.

2. Double-click on the downloaded file to begin the installation.

3. Click Yes when the installation process displays a message that asks if you want to install this Device Package.

4. The remainder of the installation process continues without any additional user input.

5. Towards the end of the install it will prompt you "Update ALL devices firmware defaults?", (IMPORTANT) If you click "yes", it will change the default firmware load for all devices to the latest load packaged with this device pack, click "no" if you want to change the loads manually yourself later.

Note: In order to change the loads manually, you do NOT need to reinstall this Device Package. The new files will be present in the C:\Program Files\Cisco\TFTPPath folder. Go to CCMAdmin->System->Device Defaults and manually change the name of the load file (for specific device(s)) to the new load and click UPDATE. Next, reset the affected devices for them to upgrade to the new load.

The system will ask you if you want to view the logfile when the installation is complete.

6. Verify that the installation completed successfully by taking the following actions:

a. When the system prompts you to view the log file, if the number of errors listed in the dialog is "0", you can select No.

b. If the number of errors detected was greater than 0, select Yes to view the logfile and scroll down to the end of the log file. The errors section at the bottom of the log file will be updated with a corresponding severity.

c. Reset affected devices in order for them to obtain new firmware loads, or reboot the cluster.

Note: If the TFTP server is a separate server from the Publisher, the Cisco TFTP service needs to be stopped and restarted on the TFTP server before performing this step, unless the cluster (including the TFTP server) is being rebooted.
