Web-based VoIP is the integration of voice over IP technologies into the facilities and methodologies of the World-Wide Web. It enables digital communication sessions between Web users, or to users of traditional telecommunication services.
Instead of using dedicated, hard-ware based VoIP devices, such as IP phones, analog telephone adapters, or integrated VoIP/Internet access routers, services are provided via a web page and the facilities of the user's computer or hand-held device for accessing and operating a locally attached head set, and microphone. This is assisted by various software components such as Flash, Active X, Silverlight, Java applet or browser plugins like NPAPI.
Using click-to-call, for example, a web user may click on a telephone number, or some other suitable icon, embedded in a corporate web site to initiate a web-based telephone call with a customer service representative without leaving the web site or using any other addition telephony equipment.
