Install a device package to introduce new phone types and upgrade the firmware for multiple phone models.
Apply this device package to all your Cisco Unified Communications Manager servers, beginning with the publisher server and
the TFTP server.
To install and upgrade all software, use the Software Upgrades menu options. The system can upload and process only Cisco
approved software. You cannot install or use third-party or Windows-based software applications that you used with a previous
version of Cisco Unified Communications Manager.
Note |
The device package is necessary to obtain configuration capability for new features and phone models. Otherwise individual
device firmware is installed with the individual device load Cisco Options Package file. You can also upload the individual
device load files to the TFTP directory. After the new files are present in the TFTP folder, restart the TFTP service from
the Cisco Unified Serviceability Web Page. Then go to CCMAdmin >Device >Device Settings >Device Defaults and manually change the name of the load file (for specific devices) to the new load. Click Save. Reset the devices.
