About the Voice & Video SDK
The Voice & Video SDK is a JQuery
The SDK is free to download
- It provides a VOIP SDK based on Cisco Web Communicator for Quad
- It provides a Web UC reference application that supports CAXL, VOIP, and WebEx working together
- It includes a reference application (and source code) that demonstrates use and power of the Web UC SDK
Architecture Overview
The SDK itself contains 3 main components:
- A native browser plugin, to provide call control and media termination within the browser
- Available on Windows and Mac, compatible with Internet Explorer, Firefox, Chrome and Safari
- Supports softphone mode (connect SIP with CUCM, use computer for audio) and deskphone mode (connect CTI with CUCM, use hardphone for audio)
- A JavaScript API to enable Cisco voice and video telephony from a web page
- The cwic jQuery plugin to access telephony features
- An optional server-side node to bring 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.
Design principles
The Jabber Voice & Video SDK depends on jQuery version 1.4 or later, and the API is available as a jQuery plugin called cwic.
Use of the cwic plugin follows the standard jQuery style of selecting one or more HTML elements, and then calling a cwic operation on the selection to manage the softphone.
cwic relies on jQuery namespacing, custom events and data to provide telephony features to a web application. cwic uses the 'cwic' namespace to name events, and data associated to HTML elements. For example, cwic triggers the 'conversationStart.cwic' event when a new conversation starts.
cwic uses the DOM (Document Object Model) as much as possible, especially to raise events and store data. For example, to start a new conversation, the application selects an HTML element to act as the conversation container. cwic uses that same element to store the conversation real-time information, and to trigger events related to this particular conversation.
