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.
NoteIf 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.
Install Firmware Release 11.0(2)SR2 on Cisco Unified Communications Manager
ProcedureBefore you can use the phone firmware release on the Cisco Unified Communications Manager, you must install the latest Cisco Unified Communications Manager firmware on all Cisco Unified Communications Manager servers in the cluster. For this release, you must also install the device pack that provides support for the Cisco Wireless IP Phone 8821.
Step 1 Go to the following URL: https://software.cisco.com/download/navigator.html?mdfid=286308995&i=rm
Step 2 Choose Cisco IP Phone 8800 Series. Step 3 Choose Cisco Wireless IP Phone 8821. Step 4 Choose Session Initiation Protocol (SIP) Software. Step 5 In the Latest Releases folder, choose 11.0(2)SR2. Step 6 Select the firmware file, click the Download or Add to cart button, and follow the prompts. Firmware file: cmterm-8821-sip.11-0-2SR2-1.k3.cop.sgn
Note If you added the firmware file to the cart, click the Download Cart link when you are ready to download the file.
Step 7 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. Step 8 Follow the instructions in the readme file to install the firmware.
Install the 11.0(2)SR2 Firmware Zip File
ProcedureIf a Cisco Unified Communications Manager is not available to load the installer program, the following .zip file is available to load the firmware:
cmterm-8821.11-0-2SR2-1.zip
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.
Step 1 Go to the following URL: http://software.cisco.com/download/navigator.html?mdfid=284883944&i=rm
Step 2 Choose Cisco IP Phones 8800 Series. Step 3 Choose Cisco Wireless IP Phone 8821. Step 4 Choose Session Initiation Protocol (SIP) Software. Step 5 In the Latest Releases folder, choose 11.0(2)SR2. Step 6 Download the relevant zip file. Step 7 Unzip the files. Step 8 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.
Install Firmware Release 11.0(2)SR2 on Cisco Unified Communications Manager Express
ProcedureYou must download the Cisco Wireless IP Phone 8821 firmware image file from the software download center.
For information on Cisco Unified Communications Manager Express support, see http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucme/feature/phone_feature/phone_feature_support_guide.html.
For more information about this procedure, refer to the "Install and Upgrade Cisco Unified CME Software" chapter in the Cisco Unified Communications Manager Express System Administrator Guide at this URL:
Step 1 To access the firmware files, go to this URL: https://software.cisco.com/download/navigator.html?mdfid=284729655&flowid=75283
Step 2 Choose Cisco Wireless IP Phone 8821. Step 3 Choose Session Initiation Protocol (SIP) Software. Step 4 Choose 11.0(2)SR2 in the Latest Releases folder. Step 5 Click Download or Add to cart and follow the prompts. The file to download is cmterm-8821.11-0-2SR2-1.zip
Step 6 Extract the files from the zip file, manually copy them to the Cisco Unified Communications Manager Express TFTP server (router flash), and enable them for TFTP.
Limitations and Restrictions
View Caveats
ProcedureYou can search for caveats using the Cisco Bug Search tool.
Known caveats (bugs) are graded according to severity level, and can be either open or resolved.
Step 1 Perform one of the following actions:
Use this URL for all caveats: https://tools.cisco.com/bugsearch/search?kw=*&pf=prdNm&pfVal=286308995&rls=11.0%282%29SR2&sb=anfr&bt=custV
Use this URL for all open caveats: https://tools.cisco.com/bugsearch/search?kw=*&pf=prdNm&pfVal=286308995&rls=11.0%282%29SR2&sb=afr&bt=custV
Use this URL for all resolved caveats: https://tools.cisco.com/bugsearch/search?kw=*&pf=prdNm&pfVal=286308995&rls=11.0%282%29SR2&sb=fr&bt=custV
Step 2 When prompted, log in with your Cisco.com user ID and password. Step 3 (Optional)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.
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 http://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.
NoteThe 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.
TipAdministrators may want to bookmark the web pages for the phone models that are deployed in their company and send these URLs to their users.
