Limitations and Restrictions

Cisco Expressway

Cisco Jabber Softphone for VDI does not support the use of Mobile Remote Access and Cisco Expressway.

Cisco Unified Communications Manager Failover

When a failover from one Cisco Unified Communications Manager to another occurs, Cisco Jabber for Windows retains phone functionality. However, with Cisco Jabber Softphone for VDI, phone functionality is lost. This issue occurs because CTI failover is not supported in the virtual environment.

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.

Jabber Features

Cisco Jabber Softphone for VDI Release 12.6 supports all Cisco Jabber for Windows Release 12.6 features, except the following:

  • Audio device selection from the Hub Menu

  • Cisco Unified Survivable Remote Site Telephony (SRST)

  • Device Selection menu on the Call Conversation window

  • Far End Camera Control (FECC)

  • Federal Information Processing Standard, Publication 140-2 (FIPS 140-2) and Information Assurance (IA) Compliance

  • Improved Video Resolution (New in Jabber for Windows Release 12.6)

  • Jabber to Jabber Call

  • 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)

  • Multiline

    Only the first line of a multiline account is available. If a second call comes in, while the first line is in use, the second line rings, but no incoming call notification appears.

  • PreferP2PDesktopShare (configuration parameter to prioritize person to person screen sharing over video sharing in the Jabber configuration file)

  • Wireless Screen Sharing (New in Jabber for Windows Release 12.6)

No Supported Upgrade Path

For more information about installation and configuration, see the Dell Wyse ThinOS documentation for your release.

SIP Profiles

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.

Performance and Behavior Notes

Camera Hot Swap

Cisco Jabber Softphone for VDI establishes video quality at the start of a call. If you start a call with one of the supported HD cameras, and then switch to a standard-definition camera, video quality is affected. We recommend that you switch cameras between calls.

Echo Cancellation

Echo cancellation is enabled only for audio calls.

Jabra Firmware

Ensure that all Jabra devices are running the latest firmware. You can use Jabra Direct to update the firmware. For more information, visit the Jabra website.

Adjust Settings for Jabra Bluetooth Devices

Most Jabra Bluetooth devices introduce a short delay in bringing up the audio path (about 1 to 3 seconds). For supported Jabra Bluetooth devices, you can eliminate the delay by changing the device settings in Jabra Direct. For more information, visit the Jabra website.
