Note for Installing older versions of the Jabber SDK Browser Add-on for Mac: - Versions of the Jabber SDK Browser Add-on prior to 3.1.0, which are using bundle-style installer packages, no longer supported on Mac OS X, can be installed by following the steps below:
  • mount CiscoWebCommunicatorAddOnInstaller.dmg
  • right click on "Cisco Web Communicator Add-On.pkg" and click "Open" in the context menu
  • click the "Open" button on the warning window
  • proceed with installation

This release of the Voice and Video SDK is compatible with Cisco Unified Communications Manager 9.0 and later, and Cisco Expressway version 8.1.1 and later

For all browsers, the cwic.js in this release of the SDK requires the use of the 11.8.0 add-on. For the Google Chrome and Mozilla Firefox browser, apps using video will need to use the new API methods to provide video functionality in the external window. In-browser video in Chrome and Firefox is no longer supported, but video overlay feature could be used for similar experience.

node Component

Download the node.csf

The node.csf provides a set of sample code to run with the node.js platform. This version of the SDK includes a new node.csf.

(Node.js is a server side web platform for building fast, scalable network applications using JavaScript. See for more information on Node.js).

The sample code adds the following Cisco Jabber SDK features to a node.js server.

  • Cisco Unified Communications Manager end user authentication
  • phone device configuration retrieval
  • directory integration

node.csf exposes an HTTP REST API and is implemented as three modules:

  • hello: replies 'hello' to clients, mainly used for testing
  • phoneconfig: authenticates Cisco Unified Communications Manager end users, retrieves list of users' phone devices, downloads phone device configuration
  • quickcontact: integrates with a directory to search for contacts
node.csf has been tested on Linux and Mac OS X.
