This document provides the procedure to upgrade Cisco IP phone firmware
individually with Cisco Unified Communications Manager 4.x/5.x/6.x .
Ensure that you meet these requirements before you attempt this
Cisco recommends that you have knowledge of these topics:

In this section, you are presented with the procedure to upgrade the
firmware of a single Cisco IP phone.
Perform these steps to upgrade the phone load for a single IP phone and
other phones to use the existing old phone load in your network environment.
This situation can arise when new firmware has to be checked before deploying
to the entire IP telephony network or any single phone that requires a feature
supported by a particular firmware.
Download the required IP phone firmware from
Cisco IP Phone - Software Download
(registered customers only)
Before you proceed to upgrade the firmware, go to the
Device menu. Choose Device Settings >
Device Defaults and copy the phone load name that you
currently use for the particular Cisco IP phone model which you are planning to
upgrade. Paste this file name in a notepad so that you can use the same file
name to revert the default phone load name to the old firmware for all other
Note: In order to get the phone load name from CallManager 4.x, go to
System > Device Defaults >
Device Defaults Configuration and copy the load
Run the upgrade patch file of the new IP phone load in Cisco
Unified CallManager. You can do this by burning the patch file to a CD or DVD,
or by sharing it via FTP or SFTP.
Go to Cisco Unified OS Administration in the
navigation menu at the top right of the web page. Login with the platform
Go to Software Upgrades >
Choose the appropriate options for DVD/CD or network source, and
provide details of where it can pull the file to download.

Device Defaults. Then, click Update.
This helps all other phones to maintain the old device default load
Go to the Device menu >Phone
and choose the IP phone on which you want to perform the upgrade. Paste the new
load information to the Phone Load Name field and click
Note: CallManager 4.x also follows this same step for changing the load
Finally you have to restart TFTP service. Go to Cisco
Unified Serviceability, then go to Tools >
Control Center-Feature Services and restart the TFTP
In order to verify that the phone has copied the new firmware image,
use one of these methods:
Find the IP address of the IP phone on which the upgrade is
performed. Use the IP address in the browser to obtain the Device information
of the IP phone. Check for the version to see if the firmware has changed to
the new one.
Physically go to the IP phone and press the Settings
button. Scroll down to Model Information and press
Select. Then, scroll down to Load File and verify that it is
the same load file which is upgraded.
