About the Voice and Video SDK

The SDK uses a browser add-on that uses the same technology as all our Jabber clients and is supported by the major Windows and Mac OSX browsers.

The SDK provides the following components:

  • Web UC reference application that supports simultaneous use of CAXL, VOIP, and WebEx working together
  • Reference application (and source code) that demonstrates the use and power of the Web UC SDK

Architecture Overview

Jabber Voice and Video SDK high-level architecture

The SDK itself contains the following components:

  • Cisco Web Communicator add-on that provides call control and media termination within the browser
    • Available on Windows and Mac operating systems
    • Compatible with Internet Explorer, Firefox, Chrome and Safari
    • Support for soft phone mode (connects SIP with Unified Communications Manager, and uses the computer for audio) and deskphone mode (connects CTI with Unified Communications Manager, and uses a physical phone for audio) and Extend and Connect mode
  • JavaScript API enables Cisco voice and video telephony from a web page
  • Optional server-side node that provides advanced features such as authentication and directory integration

The following diagram shows the high-level architecture of the SDK. This documentation describes the API exposed by the cwic jQuery plugin (cwic.js), which runs in the browser.
