API documentation


Working with the source code of the examples on your Web server


To work with demo examples on your own Apache, Nginx, Tomcat, IIS, or any other Web server,Use the latest available build of the web client:


The building looks as follows:










doc - JavaScript API documentation

examples – demo examples

flashphoner.js – the main API file you should add to your web page, it enables all supported technologies.

flashphoner-no-flash.js – the alternative API file if you don’t plan using Flash

flashphoner-no-webrtc.js - the alternative API file if you don’t plan using WebRTC

flashphoner-no-wsplayer.js - the alternative API file if you don’t plan using the Websocket player

media-provider.swf – the file to support Flash operation


We will review individual examples below.


Working with the source code of the examples directly on the WCS server


If you installed Web Call Server, you can work with the source code of the demo examples directly.


The code of the examples is located at:



To test an individual example, open the corresponding page in the browser, for example:




Here, host is the address of your WCS server.
Therefore, you can make necessary changes to the scripts and test the modified demo example directly on the WCS server.


Source code of API and examples on Github


Usually, you only need builds from the above links.

Most likely you will not need the source code. It is a last resort to make a quick fix on the API level.


In this documentation we use the source code to comment how examples work.

For example, this line 3 is a reference to the third line of the source code of package.json with the hash of 0b891b8.
