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.

Cisco Headset Management

You can manage and control your Cisco headsets from a central location on Cisco Unified Communications Manager Administration. You can:

  • Apply customized settings and control default templates

  • Track deployed headsets and to generate inventory reports

You manage the headsets in Cisco Unified Communications Manager Administration with the Device > Headsets page.

This feature requires Cisco Unified Communications Manager 12.5(1)SU1 or later, and Cisco Headset 500 Series Firmware Release 1.5(0) or later to function.

Limitations and Restrictions

Manufacturing Installed Certificate Signature and SHA-256 Support

The manufacturing installed certificate(MIC) signature has been updated from SHA-128 with RSA to SHA-256 with RSA. You must update and install the new SHA-2 certificates on the Cisco Unified Communications Manager for secure mode to function. You can download the new certificate from http://www.cisco.com/security/pki/certs/cmca2.cer.

All applications that authenticate the phone MIC should update the MIC, including the following:

  • Cisco Unified Communications Manager

  • Cisco Unified Survivable Remote Site Telephony

  • Cisco Secure Access Control System

  • Cisco Identity Services Engine

For additional information about SHA-2 use and support, see Security Guide for Cisco Unified Communications Manager (https://www.cisco.com/c/en/us/support/unified-communications/unified-communications-manager-callmanager/products-maintenance-guides-list.html).

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.

On-Hook Transfer Limitation in SIP Phones

When the Cisco Unified Communications Manager Transfer On-Hook Enabled field is enabled, users might report a problem with direct call transfer in SIP phones. If the user transfers the call and immediately goes on hook before they hear the ring signal, the call may drop instead of being transferred.

The user needs to hear the ring signal so that they can be sure that the call is being routed.

Ringtone Limitation During Firmware Downgrade from Release 11.0

When the phone downgrades from Firmware Release 11.0 to Firmware Release 10.3, the phone may not ring when there is an incoming call. The ringtone for the line has been deleted and must be manually set in the Settings > Ringtone menu.

Connections with the PC and SW Ports

If you only have one LAN cable at your desk, you can plug your phone into the LAN with the SW port and then connect your computer into the PC port.

You can also daisy chain two phones together. Connect the PC port of the first phone to the SW port of the second phone.


Caution

Do not connect the SW and PC ports into the LAN.

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.

Softkey Templates and Video Mode

You can't configure softkey templates for Video mode on the Cisco IP Phone 7800 Series phones. If a softkey appears on the phone, then it will not function correctly.

  • CSCvj80263: Sometimes the Phone will register back to vCluster after reset all on phone in hCluster

  • CSCvm44063: Phone unresponsive/frozen when connected to a laptop with CUVA setup

  • CSCvo88584: Multiple Vulnerabilities in glibc

  • CSCvp69871: 78xx media server may crash when sending buffered pre recording packets

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.
