Cisco App Software Updates
To upgrade the Cisco app software, use one of these methods:
• Install the latest signed software COP file to the Cisco Unified Communications Manager.
After you upload the COP file, the phone prompts the user to reboot and apply
the new software, unless you enabled the
Reboot immediately after downloading
software updates
option in the
Product Specific Configuration Layout
pane.
Note
• Copy the extracted firmware ZIP files contents to the HTTP (port 6970) load server defined in the
Product
Specific Configuration Layout
pane. Then, update the device default or individual phone load within
Cisco Unified Communications Manager, so that the phone upgrades after it is restarted.
