Installation
Installation Requirements
Before you install the firmware release, you must ensure that your Cisco Unified Communications Manager is running the latest device pack. After you install a device pack on the Cisco Unified Communications Manager servers in the cluster, you need to reboot all the servers.
Note |
If your Cisco Unified Communications Manager does not have the required device pack to support this firmware release, the firmware may not work correctly. |
For information on the Cisco Unified Communications Manager Device Packs, see http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/compat/devpack_comp_mtx.html.
SCCP Firmware Upgrade Issues
This section applies to the Cisco Unified IP Phones 7975G, 7971G-GE, 7970G, 7965G, 7962G, 7961G-GE, 7961G, 7945G, 7942G, 7941G-GE, 7941G, 7911G, and 7906G.
Note |
For all SCCP firmware upgrades from firmware release versions earlier than 8.3(3) to Version 9.3(1) or later, you must first upgrade your phone firmware to an intermediate version (8.3(3) to 8.5(2)) and then upgrade to 9.3(1). |
The following upgrade issues apply:
-
If you are currently running firmware earlier than 6.0(2) on a Cisco Unified IP Phone and want to upgrade to 8.x(x), you must first install an intervening 7.0(x) load to prevent upgrade failure. Cisco recommends using the most recent 7.0(3) load as the intervening load to avoid lengthy upgrade times.
-
If you are currently running firmware 6.0(2) to 7.0(2) on a Cisco Unified IP Phone and want to upgrade to 8.x(x), you can do so directly. However, expect the upgrade to take twice as long as usual.
SIP Firmware Upgrade Issues
For all SIP firmware upgrades from firmware release versions earlier than 8.3(3) to Version 9.3(1) or later, you must first upgrade your phone firmware to an intermediate version (8.3(3) to 8.5(2)) and then upgrade to 9.3(1).
The following upgrade issues apply:
-
If you are currently running firmware 6.0(2) to 7.0(2) on a Cisco Unified IP Phone and want to upgrade to 8.x(x), be aware that upgrading will take up to twice as long to complete as usual.
-
Device packs are required to enable IP Phones in the Cisco Unified Communications Manager database. For Cisco Unified CallManager 4.2 and earlier, these device packs are required. For Cisco Unified CallManager 4.3 and Cisco Unified Communications Manager 6.0 and later, you must run the device pack and reboot the Cisco Unified Communications Manager server.
Install the Firmware Release on Cisco Unified Communications Manager
Before using the Cisco Unified IP Phone 7900 Firmware Release 9.4(2)SR4 with Cisco Unified Communications Manager, you must install the latest firmware on all Cisco Unified Communications Manager servers in the cluster.

Limitations and Restrictions
Phone Behavior During Times of Network Congestion
Anything that degrades network performance can affect phone audio and, in some cases, can cause a call to drop. Sources of network degradation can include, but are not limited to, the following activities:
-
Administrative tasks, such as an internal port scan or security scan
-
Attacks that occur on your network, such as a Denial of Service attack
On-Hook Transfer Limitation in SIP Phones
When the Cisco Unified Communications Manager Transfer On-Hook Enabled field is enabled, users might report a problem with direct call transfer in SIP phones. If the user transfers the call and immediately goes on hook before they hear the ring signal, the call may drop instead of being transferred.
The user needs to hear the ring signal so that they can be sure that the call is being routed.
Language Limitation
There is no localized Keyboard Alphanumeric Text Entry (KATE) support for the following Asian locales:
-
Chinese (China)
-
Chinese (Hong Kong)
-
Chinese (Taiwan)
-
Japanese (Japan)
-
Korean (Korea Republic)
The default English (United States) KATE is presented to the user instead.
For example, the phone screen will show text in Korean, but the 2 key on the keypad will display a b c 2 A B C.
Font Limitation
Scenario
The user is set up for the English language displayed on their phone. But the corporate directory has content in a language with another character set (for example, Russian). When the user displays the corporate directory, the contents display as rectangles.
Result
The user sees characters as rectangles because the font is not available on the phone. Fonts are only available when the language locale is installed and active on the phone.
Workaround
The user needs to use the appropriate language on their phone.

Cisco Unified Communication Manager Public Keys
To improve software integrity protection, new public keys are used to sign cop files for Cisco Unified Communications Manager Release 10.0.1 and later. These cop files have "k3" in their name. To install a k3 cop file on a pre-10.0.1 Cisco Unified Communications Manager, consult the README for the ciscocm.version3-keys.cop.sgn to determine if this additional cop file must first be installed on your specific Cisco Unified Communications Manager version. If these keys are not present and are required, you will see the error "The selected file is not valid" when you try to install the software package.
Unified Communications Manager Endpoints Locale Installer
By default, Cisco IP Phones are set up for the English (United States) locale. To use the Cisco IP Phones in other locales, you must install the locale-specific version of the Unified Communications Manager Endpoints Locale Installer on every Cisco Unified Communications Manager server in the cluster. The Locale Installer installs the latest translated text for the phone user interface and country-specific phone tones on your system so that they are available for the Cisco IP Phones.
To access the Locale Installer required for a release, access https://software.cisco.com/download/navigator.html?mdfid=286037605&flowid=46245, navigate to your phone model, and select the Unified Communications Manager Endpoints Locale Installer link.
For more information, see the documentation for your particular Cisco Unified Communications Manager release.
Note |
The latest Locale Installer may not be immediately available; continue to check the website for updates. |
Cisco IP Phone Documentation Updates on Cisco Unified Communications Manager
The Cisco Unified Communications Manager Self Care Portal (Release 10.0 and later) and User Options web pages (Release 9.1 and earlier) provide links to the IP Phone user guides in PDF format. These user guides are stored on the Cisco Unified Communications Manager and are up to date when the Cisco Unified Communications Manager release is first made available to customers.
After a Cisco Unified Communications Manager release, subsequent updates to the user guides appear only on the Cisco website. The phone firmware release notes contain the applicable documentation URLs. In the web pages, updated documents display "Updated" beside the document link.
Note |
The Cisco Unified Communications Manager Device Packages and the Unified Communications Manager Endpoints Locale Installer do not update the English user guides on the Cisco Unified Communications Manager. |
You and your users should check the Cisco website for updated user guides and download the PDF files. You can also make the files available to your users on your company website.
Tip |
You may want to bookmark the web pages for the phone models that are deployed in your company and send these URLs to your users. |
