Desk phone video capabilities let users receive video transmitted to their desk phone devices on their computers through the
client. Users must physically connect the computer to the desk phone device through the computer port so that the client can
establish a connection to the device. Users cannot use desk phone video capabilities with wireless connections to desk phone
For desk phone video capabilities, you must download and install Jabber Desk Phone Video Services Interface from Cisco.com.
Jabber Desk Phone Video Services Interface provides the Cisco Discover Protocol (CDP) driver that enables the client to do
If users have both wireless and wired connections available, they should configure Microsoft Windows so that wireless connections
do not take priority over wired connections. See the following Microsoft documentation for more information: An explanation of the Automatic Metric feature for Internet Protocol routes.
Desk Phone Video Considerations
Review the following considerations and limitations before you provision desk phone video capabilities for users:
You cannot use
desk phone video capabilities on devices if video cameras are attached to the
devices, such as a Cisco Unified IP Phone 9971. You can use desk phone video
capabilities if you remove video cameras from the devices.
You cannot use
desk phone video capabilities with devices that do not support CTI.
sharing, using the BFCP protocol, is not supported with desk phone video.
It is not
possible for endpoints that use SCCP to receive video only. SCCP endpoints must
send and receive video. Instances where SCCP endpoints do not send video result
in audio only calls.
phones must use SCCP for desk phone video capabilities. 7900 series phones
cannot use SIP for desk phone video capabilities.
If a user
initiates a call from the keypad on a desk phone device, the call starts as an
audio call on the desk phone device. The client then escalates the call to
video. For this reason, you cannot make video calls to devices that do not
support escalation, such as H.323 endpoints. To use desk phone video
capabilities with devices that do not support escalation, users should initiate
calls from the client.
compatibility issue exists with Cisco Unified IP Phones that use firmware
version SCCP45.9-2-1S. You must upgrade your firmware to version SCCP45.9-3-1
to use desk phone video capabilities.
or firewall applications, such as Symantec EndPoint Protection, block inbound
CDP packets, which disables desk phone video capabilities. You should configure
your antivirus or firewall application to allow inbound CDP packets.
