Cisco Jabber Softphone for VDI

Cisco Jabber Softphone for VDI (JVDI) is the Unified Communications solution that is offered by Cisco for virtual deployments. It supports audio-video conferencing, and instant messaging on the hosted virtual desktops (HVD). The Cisco Jabber Softphone for VDI software offloads the audio or video processing from the virtual desktop servers to the thin client. All audio and video signals are routed directly between the endpoints without entering the HVD.

Cisco Jabber Softphone for VDI enables you to make and receive calls using the Cisco Unified Communications application. Cisco Jabber Softphone for VDI consists of the following two components:
  • Cisco JVDI Agent
  • Cisco JVDI Client
Cisco JVDI Agent is the JVDI connector that runs on the Citrix desktop or server. Cisco JVDI client is the JVDI package that runs on the thin client. The Jabber client that runs on the Citrix server handles the authentication and the media processing is achieved on the thin client.

Limitations
  • JVDI package cannot be installed on Dell Wyse 3030 LT, 5040, 5010, and 7010 thin clients.
  • Dell Wyse 3040 thin client supports video call up to 360p. The video call with 720p is not supported due to high CPU cost with multimedia playback simultaneously. Dell recommends that you restrict the video up to 360p in the server settings.
  • You cannot use the headset key to pick/end calls. This issue will be resolved in next release.
  • Dell does not recommend video call in 4K display resolution on all platforms due to low performance.
  • JVDI version in ThinOS 8.6 must be compatible with JVDI agent and Jabber version. For example, JVDI version 12.1 in ThinOS 8.6 supports JVDI agent and Jabber version 12.1.
  • Audio output is poor when you enable the JVDI audio during the full screen video call on Wyse 5060 and 3040 thin clients. This is due to hardware performance limitation. Wyse 5070 thin client supports full screen video call with good audio output.
NOTE: JVDI package is introduced from ThinOS version 8.6 to support Cisco Jabber. You must download the JVDI package from the Driver and Downloads tab on your respective thin clients page at www.dell.com/support. When you download the JVDI.zip package, the README WITH EULA.txt and JVDI.i386.pkg files are unzipped. Ensure that you open the readme file and read the EULA agreement before you deploy the package to the ThinOS client.

NOTE:
Table 4. Known issuesKnown issues
Issue numberDescriptionWorkaround
TIR97286 JVDI audio volume slider does not change the audio volume in Wyse 3040 thin client. This issue is due to Cisco Jabber limitation. For more information about the Cisco Jabber issues, see the Release Notes for Cisco Jabber Softphone for VDI—Release 12.1 document at www.cisco.com. Adjust audio volume by using either the ThinOS volume bar, session sound volume, or headset button.
TIR97605/TIR98498 Self-camera or remote video does not work, or a black screen is displayed when you play a video. For more information about the Cisco Jabber issues, see the Release Notes for Cisco Jabber Softphone for VDI—Release 12.1 document at www.cisco.com. Sign out of the session or reboot the ThinOS client and register the JVDI again.
TIR97653 ICA session cannot be launched and WdReceiv: trap 14 error occurs when you enable the ICA session reliability with multiport in JVDI environment. Enable ICA session reliability without enabling multiport in JVDI environment.
TIR97523 Answer/End/Hold options in headset do not work during the JVDI call. You can Answer/End/Hold the call by using the Jabber application in the VDI session.
TIR98792 DP audio does not work in JVDI. When you switch the DP audio in the JVDI device selector, the JVDI may re-register again and a redundant DP audio is listed in device selector. JVDI VXC process should not restart when you hotplug or turn off/on the monitor when using the DP audio in JVDI. Sign out of the ICA session or reboot the ThinOS client. If you require DP audio, Dell recommends that you first set the DP audio in the ThinOS client and then launch the ICA session.
