This weekend I am being tasked with installing a device pack for cisco call manager 8.5.1 (cucm 8.5.1). My question is will stage an upgrade the firmware on all of my phones within the device pack until I change the device defaults? Or is there a way I can direct the installation to not upgrade the firmware on my phones? I only need this to get my call manager to recognize a cisco ucs 8831 phone
What you can do is this:
Go to device defaults page and using your browser, save the webpage to your hard drive, this will serve as a copy of the current firmware values
Install the devpack on all nodes
Before rebooting the cluster (required for the new 8831s to register), open the device defaults page again (now showing the new firmware values)
open the old device defaults copy from your hard drive, and copy the old firmware values for each model you have (no need to modify models you don't have) into the live device defaults page, then save the changes.
Reboot the cluster.
