Important Notes
This section contains important information to consider with the Cisco Unified IP Phone 8961, 9951, and 9971.
- Cisco Unified IP Phone 9971 and Personal Address Book or Fast Dial Features
- Plantronics Audio 615M Headset and Cisco Unified IP Phone 8961
- Plantronics CS50 USB Headset and Cisco Unified IP Color Key Expansion Module
- Cisco Unified IP Phones 9951 and 9971 One-Way Video Calls
- Cisco Virtualization Experience Client 2100
- Multiple Text Messages
- No UDP for SIP Support
- Secure Video Bandwidth When Calling Over VPN
- Turn Off VPN Before Downgrade
- Firmware Update Timing
- Phone Limitation During SVI Change
- Phone Behavior During Times of Network Congestion
Cisco Unified IP Phone 9971 and Personal Address Book or Fast Dial Features
Users of the Personal Address Book or Fast Dial feature may receive an error message followed by a request to log back into the network. In DNS round robin configurations, the phone does not retain access with the same IP address. In this situation, the phone displays a message to indicate that the user must log into the phone again.
Plantronics Audio 615M Headset and Cisco Unified IP Phone 8961
The Plantronics Audio 615M headset is not compatible with the Cisco Unified IP Phone 8961. You must use an alternate headset type for this IP phone. For more information, see https://tools.cisco.com/bugsearch/bug/CSCth71104.
Plantronics CS50 USB Headset and Cisco Unified IP Color Key Expansion Module
The Plantronics CS50 USB headset causes the phone to request power from the switch even though the headset is self powered. In this case, if a device such as a camera or expansion module is connected and active on the phone, the switch will reject the power request for the headset because the power budget has been exceeded. In this case, the headset cannot be used.
Cisco Unified IP Phones 9951 and 9971 One-Way Video Calls
Because of limitations in the H.264 video signaling standards, Cisco Unified IP Phones 9951 and 9971 may not correctly display video that is received from devices supporting resolutions greater than 640 x 480. In this case, the user sees a black video screen.
To ensure that video from such devices displays properly on the IP phone, configure high definition phones and Cisco Unified IP Phones 8961, 9951, and 9971 into different call regions and limit the video bandwidth to 384 kb/s when calling between regions.
Cisco Virtualization Experience Client 2100
The Cisco Virtualization Experience Client 2100 (VXC 2100) Series are zero clients designed to deliver a user desktop from a centralized host server, providing access to desktop applications as if they were available locally. The Cisco VXC 2100 Series attaches to the Cisco Unified IP Phones 8961, 9951, and 9971 through a spine connector cable.
When running VXC with a single-tunnel option, high traffic to or from VXC may affect the phone's performance. Cisco Unified IP Phones 8961, 9951, and 9971 support 384kbps throughput bandwidth for VXC.
Set VPN MTU to 1406 to reduce packet reassemble in Cisco Unified IP Phones 8961, 9951, and 9971, to improve bandwidth in limited packet rate.
Video and audio applications may not play smoothly through VXC, even on a device plugged directly into a LAN.
USB CD-ROMs and other USB storage devices have limited support. In the current VXC environment, the expected performance is a low bit/transfer rate for USB storage devices and USB CD-ROMs connected to the VXC device.
For more information, see http://www.cisco.com/c/en/us/support/collaboration-endpoints/virtualization-experience-client-2000-series/tsd-products-support-series-home.html.
Multiple Text Messages
If you send multiple text messages to Cisco Unified IP Phones 8961, 9951, and 9971 within a few seconds using CiscoIPPhoneExecute.xml, the phone may reply with an HTTP/1.1 503 Service Unavailable message, and the user may not receive the text message on their phone screen.
No UDP for SIP Support
Cisco Unified IP Phones 8961, 9951, and 9971 do not support UDP for SIP. Do not configure the UDP protocol for SIP signaling on Cisco Unified IP Phones 8961, 9951, and 9971.
Secure Video Bandwidth When Calling Over VPN
When using Cisco Unified IP Phones 8961, 9951, and 9971 for a secure video call over VPN and VXC VPN, the maximum supported bandwidth is 320 kbps.
Turn Off VPN Before Downgrade
The phone will go into an unregistered state if it is downgraded from a 9.3(1) load to a pre-9.2(3) load while VPN is turned on. Turn off VPN before downgrading to a pre-9.2(3) load.
Firmware Update Timing
If a firmware update occurs while phones are in use, users may experience problems with their phone, such as:
Firmware updates during normal call activity are not affected.
Note | Cisco recommends that firmware updates are made during periods of inactivity. An example of a period of inactivity would be a maintenance window. |
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
Anything that degrades network performance can affect Cisco IP Phone voice and video quality, 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
To reduce or eliminate any adverse effects to the phones, schedule administrative network tasks during a time when the phones are not being used or exclude the phones from testing.
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 http://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 "Locale Installer" section in the Cisco Unified Communications Operating System Administration Guide.
Note | The latest Locale Installer may not be immediately available; continue to check the website for updates. |
