Configure Deskphone Control
Prerequisites
The Cisco CTIManager service must be running in the Cisco Unified Communications Manager cluster.
Configure Deskphone Control Taskflow
Command or Action | Purpose | |
---|---|---|
Step 1 | Enable Device for CTI
|
Allows Cisco Jabber desktop clients to control the desk phone of the user. |
Step 2 | Desk Phone Video Configuration. |
Let users receive video transmitted to their desk phone devices on their computers through the client. |
Step 3 | Enable Video Rate Adaptation
|
The client uses video rate adaptation to negotiate optimum video quality. |
Step 4 | Configure User Associations
| Associate users with devices and assign users to access control groups. |
Step 5 | Reset Devices
|
You must reset devices after you configure user associations. |
Enable Device for CTI
If you want Cisco Jabber desktop clients to be able to control the desk phone of the user, you must select the Allow Control of Device from CTI option when you create the device for the user.
Desk Phone Video Configuration
Desk phone video capabilities let users receive video transmitted to their desk phone devices on their computers through the client.
Set Up Desk Phone Video
-
Physically connect the computer to the computer port on the desk phone device.
You 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. You cannot use desk phone video capabilities with wireless connections to desk phone devices.
Tip
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.
-
Enable the desk phone device for video in Cisco Unified Communications Manager.
-
Install Cisco Media Services Interface on the computer.
Cisco Media Services Interface provides the Cisco Discover Protocol (CDP) driver that enables the client to do the following:
Note
Download the Cisco Media Services Interface installation program from the download site on cisco.com.
Desk Phone Video Considerations
-
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.
-
Video desktop 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.
-
7900 series 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.
-
A 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.
-
Some antivirus 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.
See the following Symantec technical document for additional details about this issue: Cisco IP Phone version 7970 and Cisco Unified Video Advantage is Blocked by Network Threat Protection.
-
You must not select the Media Termination Point Required checkbox on the SIP trunk configuration for Cisco Unified Communications Manager. Desk phone video capabilities are not available if you select this checkbox.
Desk Phone Video Troubleshooting
Enable Video Rate Adaptation
The client uses video rate adaptation to negotiate optimum video quality. Video rate adaptation dynamically increases or decreases video quality based on network conditions.
Note | RTCP is enabled on software phone devices by default. However, you must enable RTCP on desk phone devices. |
Enable RTCP on Common Phone Profiles
You can enable RTCP on a common phone profile to enable video rate adaptation on all devices that use the profile.
Note | RTCP is an integral component of Jabber Telephony services. Jabber will continue to send RTCP packets even when disabled. |
Enable RTCP on Device Configurations
You can enable RTCP on specific device configurations instead of a common phone profile. The specific device configuration overrides any settings you specify on the common phone profile.
Configure User Associations
When you associate a user with a device, you provision that device to the user.
Reset Devices
After you create and associate users with devices, you should reset those devices.
