Web-based VoIP is based on the concept of click to talk, which is a form of Web-based communication in which a person clicks an object (i.e. button, image, or text) to request an immediate connection with another person in real-time either by phone call, Voice-over-Internet-Protocol (VoIP), or text. Click to talk requests are most commonly made through websites but can also be initiated by hyperlinks placed in email, blogs, wikis, flash animations, or video, and other Internet-based object or user interface.
Web-based VoIP uses the existing VoIP infrastrucuture but links the web object, which can be shown as Flash, Active X, or Silverlight by any kind of web page.
Call flow
Caller goes to a webpage and find the destination the caller want to communicate, a caller will be required or without a login process for identification, then click the object from the webpage which already connect to a phone or IP number, meanwhile, caller will also automatically allocate a caller number to make the communication link to the call receiver.
Current market
Web-based VoIP can be used for any kind of web communication services, such as yellow page service, web conference, eMap, web toll free number or e-learning technology. The usage of web-based VoIP is increasing everyday and so with the number of products being released everyday. Recently, in an article written by Mark Gibbs, author at Network World, he mentioned about a new web-based VoIP product "Push2Call" that may out-beat the purpose of Click-to-call.[1]
