Cisco Unified Wireless IP Phone 7925G Series Deployment Guide 79
Upgrading Phone Firmware
There are two methods for upgrading the Cisco Unified Wireless IP Phone 7925G Series firmware, which is either via wireless
TFTP or the phone web interface.
Wireless TFTP
To upgrade the phone firmware, run the executable for Cisco Unified Communications Manager version 4.1, 4,2 and 4.3 or
install the COP file for versions 5.1, 6.0, 6.1, 7.0, 7.1, 8.0 and later.
For information on how to install the COP file on CM versions 5.1 and later, refer to the Cisco Unified Communications
Manager Operating System Administrator Guide at this URL:

During TFTP server download, the phone configuration file is parsed and the device load is identified. The phone
downloads the firmware files to flash if it is not running the specified image already.
Cisco Unified Communications Manager device load takes precedence over the TFTP firmware version.
The Load Server can be specified as an alternate TFTP server to retrieve firmware files in the Cisco Unified Wireless IP Phone
7925G Series product specific configuration in Cisco Unified Communications Manager Administration.
To install the firmware on Cisco Unified Communications Manager Express, extract the contents of the TAR file and upload
into the router’s flash. Each file will need to be enabled for TFTP download. Configure the phone load and reset the phones to
upgrade the firmware.
