Introduction to webphone technology

A webphone is a softphone solution that is embedded into your web page.

They only have to visit your page and they can call you directly from their browser.

  • Web page
    Webphones are embedded into a web page, so you will definitely need one for using this service.
  • Flash/Silverlight support
    The webphone client applications have multimedia content, therefore they need some support for displaying this content on the web.
  • Webphone server
    The webphone server is a solution that provides the communication establishment between two webphone applications or between a webphone and a softphone or with the use of the PSTN between a webphone and an analog or mobile phone.

The webphone client application is embedded in a web site and when a user calls a number the client that is also connected to the server over some standard protocols (NET.TCP, HTTP, RTMP, etc.) sends the call message to the server that transfers it to a remote client or a SIP softphone.

The webphone server is a software solution that provides all the needed services towards the webphone client application. The basic function of a webphone server is to establish the connection between the two parties and to forward the voice between them.

Flash technology is one of the most frequently used client-side technique for client-side dynamic multimedia content visualization nowadays.
Flash ensures the animation of texts, drawings or even images by manipulating vector and raster graphics. With Flash, the support of bidirectional streaming of audio and video is available. In addition, it can capture user input through mouse, keyboard, microphone and camera. Flash contains an object-oriented language that is called ActionScript. It also supports automation via the Javascript Flash language (JSFL).
Ozeki SIP SDK enables you to boost Flash technology and to develop Flash webphones: How to add a webphone to a webpage (Flash camera and microphone access).

Microsoft Silverlight has been basically designed for replacing Flash technology and provides mostly the same features as Adobe Flash does.
Microsoft Silverlight is a multimedia tool for displaying media streams mainly embedded into web pages. It has its own method set and can be programmed from Visual Studio, therefore this technology does not require you to have different development environment for the client and the server solution programming.
