Using Asterisk PBX for Web Conferencing

Today when organizations are distributed at various locations, getting everyone together is a bit difficult at times. For instance, in case of most of the organizations, sometimes half of the team of a company would be based somewhere in the US, and half in some other part of the world. In such cases, web conferencing is a savior! Web conferencing technology is now a mainstream medium through which individuals or groups can meet face-to-face in real time to interact.

Web conferencing technology supports sharing of slides (PDF and PPT), video, whiteboard, chat, voice using Asterisk PBX, and desktops.

Web Conferencing features include the following:

Asterisk based web conferencing allows instantaneous conference calling where the user can select any group of contacts, or any e-mail or calendar appointment and automatically initiate a conference call to all the recipients
• Web conferencing allows to join the Asterisk VOIP based voice conference from within the client using a built-in SIP phone
Hosted Asterisk based web conferencing allows chat with other users including private chat
• Web conferencing facilitates to view the presenter’s slides and cursor
• It helps share a video stream (webcam) with other participants
• Web conferencing also facilitates uploading of slides (PDF or any office document supported by Open Office)
• In web conferencing, the presenter can mute or eject listeners from the voice conference. In web conferencing, the presenter can share their desktop (yes, even on Linux).

Also, don’t forget to enjoy the benefits of the best application hosting solutions, such as hosted VOIP PBX, Microsoft Exchange, SharePoint, etc., which has become the preferred way for companies to implement business software.

A DHTML webpage is any webpage in which client-side scripting changes variables of the presentation definition language, which in turn affects the look and function of otherwise “static” HTML page content, after the page has been fully loaded and during the viewing process. Thus the dynamic characteristic of DHTML is the way it functions while a page is viewed, not in its ability to generate a unique page with each page load.
