Firmware Limitation of Cisco IP Conference Phone 8832 with Cisco IP Conference Phone 8832 PoE Injector
The Cisco IP Conference Phone 8832 PoE Injector is supported on phones running firmware release 12.0(1)SR2 and later. Confirm that the latest firmware release is installed on the Cisco Unified Communications Manager before you connect the Cisco IP Conference Phone 8832 with the PoE injector to the network.
If you are not using the latest firmware release, then your phone may downgrade to an earlier firmware release, and lose the network connectivity.
To recover a phone that has lost network connectivity, update Device Defaults for the Cisco IP Conference Phone 8832 to 8832-sip.12-0-1SR2-2.k3.cop.sgn or later in Cisco Unified Communications Manager Administration. Then, perform one of the following steps:
-
Force the phone to reboot from the alternate software image that supports the PoE Injector. To reboot your phone from the backup image, see Boot Up the Conference Phone from the Alternate Partition section in the Cisco IP Conference Phone 8832 Administration Guide for Cisco Unified Communications Manager.
-
Install and use the Cisco IP Conference Phone 8832 Ethernet Injector on the phone. This allows you to regain network connectivity. After the phone has upgraded to the latest firmware, you can again use the Cisco IP Conference Phone 8832 PoE Injector.
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.
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.
Wireless Microphone Battery Limitation
When you press the Show detail softkey, the Cisco IP Conference Phone 8832 occasionally displays a false Bad battery warning. This issue occurs when you quickly reseat the wireless microphone 20 consecutive times or more.
To recover from this issue, perform the following steps in order:
-
Remove the microphone from the charging cradle.
-
Press the Mute button for approximately 10 seconds or until the microphone LED stops blinking white. Then, reseat the microphone on the charging cradle.
-
Restart the phone by disconnecting and reconnecting the Cisco IP Conference Phone 8832 Power Adapter.
The Bad battery warning on the phone screen disappears and the current battery status appears. If you do not see the battery status, then the microphone battery has deteriorated and you must replace it.

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. |
