with the Firmware Release
The following sections describe the features available with the Firmware
Audio Clock Frequency
The frequency of the audio clock has changed to 12.288 MHz in the firmware. This frequency change doesn’t change the functionality or configuration of the phone.
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.
If your Cisco Unified Communications Manager does not have the required device pack to support this firmware release, the firmware may not work correctly.
Select the firmware file, click the Download or Add to cart button, and follow the prompts.
The firmware filename is cmterm-8832-sip.12-0-1SR3-1.k3.cop.sgn.
If you added the firmware file to the cart, click the Download Cart link when you are ready to download the file.
Click the + next to the firmware file name in the Download Cart section to access additional information about this file. The hyperlink for the readme file is in the Additional Information section, which contains installation instructions for the corresponding firmware.
Follow the instructions in the readme file to install the firmware.
Install the Firmware Zip Files
If a Cisco Unified Communications Manager is not available to load the installer program, the following .zip file is available to load the firmware:
Firmware upgrades over the WLAN interface may take longer than upgrades using a wired connection. Upgrade times over the WLAN interface may take more than an hour, depending on the quality and bandwidth of the wireless connection.
Manually copy the unzipped files to the directory on the TFTP server. See Cisco Unified Communications Operating System Administration Guide for information about how to manually copy the firmware files to the server.
Limitations and Restrictions
Phone Behavior During Times of Network Congestion
Anything that degrades network performance can affect phone voice and video quality, 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
This product is not a
medical device and uses an unlicensed frequency band that is susceptible to
interference from other devices or equipment.
There is no localized Keyboard
Alphanumeric Text Entry (KATE) support for the following Asian
Chinese (Hong Kong)
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.
You can search for caveats using the Cisco Bug Search.
Known caveats (bugs) are graded according to severity level, and can be either open or resolved.
When prompted, log in with your Cisco.com user ID and password.
Enter the bug ID number in the Search for field, then press Enter.
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.
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.
For more information, see the documentation for your particular Cisco Unified Communications Manager release.
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.
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.
Administrators and users should check the Cisco website for updated user guides and download the PDF files. Administrators can also make the files available to the users on their company website.
Administrators may want to bookmark the web pages for the phone models that are deployed in their company and send these URLs to their users.
