Security Enhancements

You can improve security over phones that act as an HTTPS server. With the parameter Disable TLS1.0 and TLS1.1 for web access, you can apply TLS1.0, TLS1.1, and TLS 1.2 mode, or just TLS 1.2 mode to any phone, or group of phones that function as an HTTPS server.

For other configurations, you configure TLS protocols on the Cisco Unified Communications Manager. As of Cisco Unified Communications Manager Release 12.0, there are TLS settings configured by a CLI command. See Release Notes for Cisco Unified Communications Manager and IM & Presence Service, Release 12.0(1) for information about new CLI commands on Cisco Unified Communications Manager.

You set the Disable TLS1.0 and TLS1.1 for web access field in the Product Specific Configuration Layout pane of your Cisco Unified Communications Manager. Install the latest device package for this feature to function.

The ability to disable TLS1.0 and TLS1.1 is supported on Cisco Unified Communications Manager Release 11.5(1)SU3 and later.

Also included in this feature are:

- Support for the Cisco Discovery Protocol (CDP).

- Removal of all the IPv6 configuration fields displayed on Cisco Unified Communications Manager and on the phone.

Where to Find More Information

- Cisco Wireless IP Phone 8821 and 8821-EX Administration Guide

Serviceability Enhancements

You can support your users with these new functions:

- You can use the Audio Diagnostics function to troubleshoot audio problems.

- You can configure Problem Report Tool (PRT) reports to automatically upload to a remote server.

- You can request a PRT with the X/Open System Interface (XSI) CiscoIPPhoneExecute object.

- You can request a PRT from the phone administration web page.

- You can generate and delete Java core dumps from the phone administration web page.

- Cisco Unified IP Phone Services Application Development Notes for Cisco Unified Communications Manager and Multiplatform Phones

User Interface Enhancements

You control the following user interface changes:

- You can control if the Decline softkey displays when the users have incoming calls.

To support the Decline function, you set the Divert Alerting Call field in the Product Specific Configuration pane of the Cisco Unified Communications Manager Administration Device > Phones page.

- You can control if an active phone can vibrate when it receives the Vibrate URI command in an XSI message. By default, the phone doesn't vibrate.

To enable phones to vibrate, you enable the Allow Vibrate URI When On Call field in the Product Specific Configuration pane of the Cisco Unified Communications Manager Administration Device > Phones page.

- Battery information displays in the phone web page and in the Status menu on the phone.

Users will experience the following changes:

- When the phone is in the Cisco Wireless IP Phone 8821 Desktop Charger, the ringer can now be set to a higher volume level.

- The header row of the screen can display the battery charge level as a percentage beside the generic icons. The field Battery percentage in the Settings menu on the phone controls the display of the percentage charge level.

- Users can add or update local contacts from the Recents app.

- Users see the Favorites softkey on the main screen for quick access to the Favorites list. The Favorites list is also available from the Contacts app.

- In the Local contacts list, users see the Delete option when they highlight a contact and press More . In the previous release, the Delete option was only available on the Details screen.

Entries in the phone configuration menus and the phone web page related to IPv6 don't display. The phone doesn't support IPv6.

Limitations and Restrictions

- Phone Behavior During Times of Network Congestion

- Health-Care Environment Use

- Recording Tone Volume Limitation

- TLS 1.2 Tunnel Limitation with ISE 2.0 to 2.3

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.

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.

TLS 1.2 Tunnel Limitation with ISE 2.0 to 2.3

To support a TLS 1.2 tunnel between the phone and the Cisco Identity Service Engine (ISE) server, the ISE patch to resolve CSCvm03681 must be applied. This patch is required for ISE servers running Release 2.0 to 2.3; ISE Release 2.4 and later include the patch.

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.
