Prerequisites
The Cisco CTIManager service must be running in the Cisco Unified Communications Manager cluster.
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

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.

In Cisco Unified CM Administration, click and search for the phone. |
Step 2 |
In the Device Information section, check Allow Control of Device from CTI. |
Step 3 |
Click Save. |
Desk phone video capabilities let you receive the video signal on your laptop and the audio signal on your desk phone. Physically connect your computer to the desk phone through the computer port for the client to establish a connection to the Jabber client. You cannot use this feature with a wireless connection to your desk phone.
Note |
If you have both wireless and wired connections available, configure Microsoft Windows to not prioritize wireless connections over wired connections. See Microsoft's An explanation of the Automatic Metric feature for Internet Protocol routes for more information. |
First, 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. CDP enables the client to:
Discover the desk phone.
Establish and maintain a connection to the desk phone using the Cisco Audio Session Tunnel (CAST) protocol.
Desk Phone Video Considerations
Review the following considerations and limitations before you set up the desk phone video feature:
You cannot have more than one video device connected with CAST. You cannot use a desk phone with a built-in camera with this feature. If your desk phone has a local USB camera, remove it before using this feature.
You cannot use this feature with devices that do not support CTI.
You cannot use both video screen sharing, using the BFCP protocol, and 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 a video signal 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 you start a call from a desk phone's keypad, the call starts as an audio call on the desk phone. Jabber then escalates the call to video. For this reason, you cannot make video calls to devices that do not support the escalation, such as H.323 endpoints. To use this feature with devices that do not support escalation, begin calls from the Jabber client.
A compatibility issue exists with Cisco Unified IP Phones that use firmware version SCCP45.9-2-1S. Upgrade your firmware to version SCCP45.9-3-1 to use this feature.
Some antivirus or firewall applications, such as Symantec EndPoint Protection, block inbound CDP packets. This blockage disables desk phone video. Configure your antivirus or firewall application to allow inbound CDP packets.
See the following Symantec technical document for more details about this issue: Cisco IP Phone version 7970 and Cisco Unified Video Advantage is Blocked by Network Threat Protection.
Do not select the Media Termination Point Required check box on the SIP trunk configuration for Cisco Unified Communications Manager (Unified CM). That setting disables desk phone video.
Step 1 |
Physically connect your computer to the computer port on your desk phone. |
Step 2 |
Enable the desk phone for video in Unified CM. |
Step 3 |
Install Jabber Desk Phone Video Services Interface on your computer. |
If you encounter an error that indicates desk phone video capabilities are unavailable or the desk phone device is unknown, do the following:
Ensure you enable the desk phone device for video in Cisco Unified Communications Manager.
Reset the physical desk phone.
Exit the client.
Run services.msc on the computer where you installed the client.
Restart Jabber Desk Phone Video Services Interface from the Services tab of the Windows Task Manager.
Restart the client.
You must add directory numbers to devices in Cisco Unified Communications Manager. This topic provides instructions on adding directory numbers using the menu option after you create your device. Under this menu option, only the configuration settings that apply to the phone model or CTI route point display. See the Cisco Unified Communications Manager documentation for more information about different options to configure directory numbers.
Step 1 |
Locate the Association Information section on the Phone Configuration window. |
Step 2 |
Select Add a new DN. |
Step 3 |
Specify a directory number in the Directory Number field. |
Step 4 |
Specify all other required configuration settings as appropriate. |
Step 5 |
Associate end users with the directory number as follows: |
Step 6 |
Select Save. |
Step 7 |
Select Apply Config. |
Step 8 |
Follow the prompts on the Apply Configuration window to apply the configuration. |
The client uses video rate adaptation to negotiate optimum video quality. Video rate adaptation dynamically increases or decreases video quality based on network conditions.
To use video rate adaptation, you must enable Real-Time Transport Control Protocol (RTCP) on Cisco Unified Communications Manager.
Note |
RTCP is enabled on software phone devices by default. However, you must enable RTCP on desk phone devices. |
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. |
Step 1 |
Open the Cisco Unified CM Administration interface. |
Step 2 |
Select .The Find and List Common Phone Profiles window opens. |
Step 3 |
Specify the appropriate filters in the Find Common Phone Profile where field and then select Find to retrieve a list of profiles. |
Step 4 |
Select the appropriate profile from the list. The Common Phone Profile Configuration window opens. |
Step 5 |
Locate the Product Specific Configuration Layout section. |
Step 6 |
Select Enabled from the RTCP drop-down list. |
Step 7 |
Select Save. |
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.
Step 1 |
Open the Cisco Unified CM Administration interface. |
Step 2 |
Select .The Find and List Phones window opens. |
Step 3 |
Specify the appropriate filters in the Find Phone where field and then select Find to retrieve a list of phones. |
Step 4 |
Select the appropriate phone from the list. The Phone Configuration window opens. |
Step 5 |
Locate the Product Specific Configuration Layout section. |
Step 6 |
Select Enabled from the RTCP drop-down list. |
Step 7 |
Select Save. |
When you associate a user with a device, you provision that device to the user.
