Limitations and Restrictions
DTMF During On-Hook Dialing
On-hook dialing can result in users hearing the DTMF from the key press in the handset. The tones are heard if the handset is picked up while the last digit is pressed. If users pick up the handset after pressing the last digit, they will normally not hear any DTMF.
Voice VLAN and IPv6 Limitation
If the PC attached to the PC port of the phone is using IPv6, we recommend that the PC Voice LAN access be disabled. This ensures that the PC cannot connect to the Voice VLAN.
Phone Limitation During SVI Change
Cisco IP Phones use a Switch Virtual Interface (SVI) to manage VLANs. If the SVI changes and the phones require new IP addresses, some phones require a reboot so that the new IP address is used. The following phones must be rebooted in this condition:
-
Cisco Unified IP Phone 6901
-
Cisco Unified IP Phone 6911
-
Cisco Unified IP Phone 6921
-
Cisco Unified IP Phone 6941
-
Cisco Unified IP Phone 6945
-
Cisco Unified IP Phone 6961
-
Cisco Unified IP Phone 8941
-
Cisco Unified IP Phone 8945
-
Cisco Unified IP Phone 8961
-
Cisco Unified IP Phone 9951
-
Cisco Unified IP Phone 9971
Phone Behavior During Times of Network Congestion
-
Administrative tasks, such as an internal port scan or security scan.
-
Attacks that occur on your network, such as a Denial of Service attack.
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.

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. |
