Your phone supports accessories from Cisco and third-party
Cisco Unified IP Phone

Each USB port supports a maximum of five supported and nonsupported devices that are connected to the phone. Each device connected to the phone is included in the maximum device count.
For example, your phone can support five USB devices (such as three Cisco Unified IP Color Key Expansion modules, one hub, and one other standard USB device) on the side port and five additional standard USB devices on the back port. Many third-party USB products contain more than one USB device, and thus count as more than one device. For example, a third-party USB device may contain an internal hub and a headset, and thus count as two USB devices.
If you use a USB hub and remove the USB cable from the phone or device port during an active call, it may cause your phone or device to reboot. For more information, contact your system administrator.
Cisco Unified IP Color Key Expansion Module
The Cisco Unified IP Color Key Expansion Module attaches to your Cisco Unified IP Phone 8961, 9951, and 9971 and allows you to add up to 36 extra line appearances or programmable buttons to your phone. The programmable buttons can be set up as phone line buttons, speed-dial buttons, or phone feature buttons.
You can add multiple Expansion Modules to the Cisco Unified IP Phone 9951 and Cisco Unified IP Phone 9971.
Cisco Unified IP Phone model
Number of Expansion Modules supported
1 Expansion Module with 36 lines or buttons
2 Expansion Modules with 72 lines or buttons
3 Expansion Modules with 108 lines or buttons
When multiple Expansion Modules are attached, they are numbered according to the order in which they are connected to the phone. For example:
Key Expansion Module 1 is the Expansion Module closest to the phone.
Key Expansion Module 2 is the Expansion Module in the middle.
Key Expansion Module 3 is the Expansion Module farthest to the right.

Cisco Unified Video Camera
The Cisco Unified IP Phone 9951 and 9971 support the Cisco Unified Video Camera.
The Cisco Unified Video Camera connects to your Cisco Unified IP Phone and allows you to make a point-to-point video call with another Cisco Unified IP Phone with a Cisco Unified Video Camera attached. If a phone does not have a Cisco Unified Video Camera attached, it can receive only one-way video.
The Cisco Unified IP Phone 8961 does not support the Cisco Unified Video Camera and does not display video.
The following figure shows the Cisco Unified IP Phone 9951 and Cisco Unified Video Camera.
The following figure shows the location of the camera lens shutter.
To close the shutter, rotate the lens clockwise.
To open the shutter, rotate the lens counterclockwise.
Cisco Unified Video Camera Installation
The Cisco Unified Video Camera can be mounted on your Cisco
Unified IP Phone 9951 or 9971, or it can be mounted on your computer monitor.
If you need help installing or positioning your camera, contact your system
The Enable Video On/Off settings in the phone menu controls the ability to control the video capability of the phone. If you enabl video, you identify the phone as being capable of sending and receiving video. If you disable video, your calls use only audio.

The Cisco Unified IP Phone 9951 and 9971 support Bluetooth Class 2 technology when the headsets support Bluetooth. Bluetooth enables low-bandwidth wireless connections within a range of 30 feet (10 meters). The best performance is in the 3- to 6-foot (1- to 2-meter) range.
When using Bluetooth headsets with your phone, these conditions apply:
You can pair and connect up to five Bluetooth headsets to your phone, but the last Bluetooth headset connected becomes the default for use with the phone.
After a Bluetooth headset is connected, turning it off and reconnects it to the phone. The following instructions apply when using the Bluetooth headset:
If you have both a Bluetooth headset and an analog headset attached to the phone, only one type of headset works at any time. Using a USB headset disables both the Bluetooth and analog headset.
Enable the Bluetooth headset to disable the analog headset.
Disable the Bluetooth headset to enable the analog headset.
Unplug the USB headset and then enable either the Bluetooth headset or the analog headset.
For optimum headset coverage, use your Bluetooth headset within 10 ft of the phone, although Bluetooth coverage extends to about 30 ft from the phone.
Your phone supports the Bluetooth Handsfree Profile. If your Bluetooth headset supports these features, you can perform these call functions from your Bluetooth headset:
Answer a call
End a call
Change the headset volume for a call
Hold and Accept
Release and Accept
For more information, see the documentation from your Bluetooth headset manufacturer.
While using Bluetooth headset, there can be potential interference issues. Therefore Cisco recommends that you reduce the proximity of other 802.11b/g devices, Bluetooth devices, microwave ovens, and large metal objects.
For a Bluetooth wireless headset to work, it does not need to be within direct line-of-sight of the phone, but some barriers, such as walls or doors, and interference from other electronic devices, can affect the connection.
The Virtual Desktop Infrastructure (VDI) client attaches to
the Cisco Unified IP Phone 8961, 9951, or 9971. It provides a virtual
environment that allows you to work and collaborate from any device and
location at any time.
You must use the Cisco IP Power Cube on the phone in order to use the VDI client.
