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.

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.

Phone Data Migration Limitation for Cisco Unified Communications Manager Software Release 11.5SU8

The Phone Data Migration feature in Cisco Unified Communications Manager 11.5SU8 is not localized. Parameters and other items may not display in your native language. The limitation does not apply to information displayed on the phones.

Localization is complete for Cisco Unified Communications Manager Software Release 12.5(1)SU3 and later.

Application Programming Interface

Cisco supports phone API utilization by 3rd party applications that have been tested and certified through Cisco by the 3rd party application developer. Any phone issues related to uncertified application interaction must be addressed by the 3rd party and will not be addressed by Cisco.

For support model of Cisco certified 3rd party applications/solutions, please refer to Cisco Solution Partner Program website for details.

Cisco Unified Communication Manager Public Keys

To improve software integrity protection, public keys are used to sign cop files for Cisco Unified Communications Manager Release 10.0.1 and later. These cop files have "k3 or k4" in their name. To install a k3 or k4 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 you must install this additional cop file 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 the Software Download page, 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.
