To get the new Cisco Jabber Softphone for VDI features, you must upgrade all of the following components to the current release:
Cisco Jabber for Windows
Cisco JVDI Agent
Cisco JVDI Client
Both the Cisco JVDI Agent and Cisco JVDI Client are required for softphone registration to succeed. The Cisco Jabber for Windows and the Cisco JVDI Agent versions must always match. However, the Cisco JVDI Client version can be the same, or up to two releases earlier. The earlier software version determines the available feature set.
