New and Changed Features
The following sections describe the features that are new or have changed in this release.
Note
Some features may require the installation of a Cisco Unified Communications Manager Device Package. Failure to install the Device Package before the phone firmware upgrade may render the phones unusable.
Features Available with the Firmware Release
The following sections describe the features available with the Firmware Release.
Bulk Deployment Utility
The Bulk Deployment Utility (BDU) for the Cisco Wireless IP Phone 8821 and 8821-EX can be used for initial deployment or after the phones have been deployed. The BDU provides quick provisioning and deployment when unique 802.1x accounts are used with EAP-FAST, PEAP-GTC, or PEAP-MSCHAPV2 or when a common set of credentials are used by all phones (for example, PSK or a single 802.1x account).
The BDU requires Firmware Release 11.0(3)SR4 or later on the phones.
Note
This version of the BDU is not the same as the BDU for the Cisco Unified Wireless IP Phone 792x Series.
You download the BDU from this location:
https://software.cisco.com/download/type.html?mdfid=286308995&flowid=80142
For more information, see the Bulk Deployment Utility Guide for Cisco Wireless Phone 8821 and 8821-EX located here: https://www.cisco.com/web/software/282074239/14006/882xBD.1-0-readme.pdf.

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.

Limitations and Restrictions
Phone Behavior During Times of Network Congestion
Health-Care Environment Use
This product is not a medical device and uses an unlicensed frequency band that is susceptible to interference from other devices or equipment.
Recording Tone Volume Limitation
If you use the recording feature, we recommend that you change the Recording Tone Local Volume configured in Cisco Unified Communications Manager. Change the field from the default of 100 to 20.
The CUCM device packs (October 2017 and later) have the default set to 20.
For more information, look at CSCvc14605 using https://tools.cisco.com/bugsearch.
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.
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.
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.
