General Limitations and Restrictions
Accessory Call Control
Accessory call control (adjust call volume, answer or end phone calls, and mute audio) is supported for compatible headsets. Some other headsets provide basic functionality, but the accessory call control features do not work with Cisco Jabber Softphone for VDI. For a complete list of compatible headsets and other accessories, see https://www.cisco.com/c/en/us/products/unified-communications/uc_endpoints_accessories.html.
Call Preservation Mode
Cisco Jabber Softphone for VDI does not support Call Preservation, also known as "survivability". If a network interruption occurs and Cisoc Jabber goes into Call Preservation mode, the calls drop for VDI users.
Changes to Your Connection Method
You must always install Citrix or VMware before you install the JVDI Client. Therefore, you must reinstall the JVDI Client after one of the following changes:
Upgrading Citrix or VMware
Switching from Citrix to VMware, or from VMware to Citrix

Cisco Jabber desk phone video (display of video on the desktop when the thin client is connected to the user's desk phone)
Kerberos and Common Access Card (CAC) with Single Sign On (SSO)
Cisco Jabber Softphone for VDI does not support CAC, and supports Kerberos only with SSO.
PreferP2PDesktopShare (configuration parameter to prioritize person to person screen sharing over video sharing in the Cisco Jabber configuration file)
Wireless Screen Sharing
XMPP Federation for Team Messaging Mode
Cisco Media Services Interface and Dual VLAN
Cisco Media Services Interface (MSI) and Dual VLAN are not supported for this release.
HDX RealTime Webcam with Citrix
Cisco Jabber Softphone for VDI does not support HDX Plug-n-Play for cameras. Citrix recommends using HDX Webcam for camera interactions.
Microphone Levels in Fallback Mode
Microphone levels are reset to 54% in VDI fallback mode when a user unplus and replugs a headset. This is a Citrix audio device mapping issue.
Multiple Hosted Virtual Desktop Sessions
Cisco Jabber Softphone for VDI may not work as expected with multiple HVD sessions. The phone service connection should be unaffected but the video or self-view position might be incorrect when in a call or when previewing the video.
Remote Display Protocol Support
Cisco Jabber Softphone for VDI supports only the following protocols:
VMware: PC-over-IP (PCoIP) and VMware Blast Extreme
Remote Problem Report Tool (PRT)
The remote PRT feature won't work when the virtual channel connection is broken.
Self View in Fallback Mode
In VDI fallback mode, the self view may not appear with Citrix HDX Web Camera, or VMware Virtual Webcam,
Single Session Hosted Virtual Desktop (Windows Server 2019)
Cisco Jabber Softphone for VDI 12.9(1) doesn`t support Windows 2019 as a single session hosted virtual desktop (HVD). If Windows 2019 is a single-session desktop in the VMware VDI environment, use the following workaround when Jabber for Windows isn't runing in VDI mode.
Add the following to the Windows registries on the HVD:
[HKEY_CURRENT_USER\Software\Cisco Systems, Inc.\JVDI] "isVDIEnabled"="true"
After you edit the registry, restart Cisco Jabber.
When you create a Cisco Unified Client Services Framework (CSF) device, you specify a SIP Profile for the device. SIP profiles provide specific SIP information for the phone, such as registration and keepalive timers, media ports, and Do Not Disturb control.
If you choose Secure Phone Profile, do not specify the Certificate Authority Proxy Function (CAPF) authentication mode By Null string. Use of this setting, with Cisco Jabber Softphone for VDI, causes Cisco Jabber registration with Cisco Unified Communications Manager to fail.
USB Camera Redirection Not Supported with VMware View
USB camera redirection is not supported with VMware View.
Cisco Jabber Softphone for VDI 12.8 and later supports Display Scaling mode. Users should check their VMware Options menu and ensure that Allow Display Scaling is checked.
Cisco Jabber Softphone for VDI supports full-screen and windowed display for Windows and Linux thin clients in both VMWare and Citrix VDI environments.
Voice Message Recording
In a Windows Server 2019 environment, Cisco Jabber Softphone for VDI may not be able to record a voice message. To fix this issue, check the microphone privacy settings on the HVD and allow apps to access the microphone if needed.
