The CP-9971-C-K9 includes a 10/100/1000BASE-T Ethernet connection and an integrated switched PC port. The PC port allows a connected computer to share the network connection provided to the IP phone, which can simplify cabling at the user’s desk.
In managed enterprise networks, the phone can be integrated with voice and data VLAN configurations. Cisco network discovery and power-management technologies such as CDP and LLDP-PoE help the device operate within supported Cisco network environments.
802.11a/b/g Wi-Fi Connectivity
The Cisco CP-9971-C-K9 includes integrated 802.11a/b/g Wi-Fi support for compatible wireless deployments. Wireless connectivity can be useful in offices where Ethernet cabling is limited or where flexible desk placement is required.
Wireless deployment should be planned carefully. Organizations should verify the supported wireless security configuration, available network bands, authentication requirements and power method before installing the phone over Wi-Fi.
When the phone is used through Wi-Fi instead of a powered Ethernet connection, an appropriate Cisco power accessory may be required. Power requirements should be confirmed according to the exact deployment configuration.
Bluetooth and USB 2.0 Support
The Cisco CP-9971-C-K9 supports Bluetooth and provides two USB 2.0 ports. These interfaces extend the phone’s accessory capabilities and can be used with supported headsets, peripherals and the compatible Cisco Unified Video Camera.
Bluetooth connectivity can be useful for users who prefer wireless audio accessories, while USB connectivity provides additional flexibility for supported Cisco accessories and enterprise desk configurations.
HD Voice and Audio Features
The Cisco 9971 was designed to provide high-quality business voice communication with HD voice support. Supported audio capabilities extend across the handset, speakerphone and compatible headset configurations.
The phone also supports hands-free speakerphone operation, making it suitable for individual desk communication and smaller collaborative conversations. Audio codec support depends on the call-control platform and firmware configuration.
Video Support with Cisco Unified Video Camera
The Cisco CP-9971-C-K9 is a video-capable IP phone, but the standard phone configuration should not be described as having a built-in camera. Video communication requires the compatible Cisco Unified Video Camera accessory.
Cisco documents H.264/AVC video support with frame rates of up to 30 frames per second and support for video formats including VGA and lower resolutions. This allows the 9971 to support video communication when the appropriate camera, firmware and Cisco Unified Communications environment are available.
Customers should confirm whether the Cisco Unified Video Camera is included with the unit or must be purchased separately. For refurbished products, the condition and availability of the camera should also be verified.
