iSymphony is a web based application that runs an embedded web server in order to provide client functionality within a user's browser.
If you are building a new phone system and are considering iSymphony in your plans, we recommend using the FreePBX distribution.
Symphony requires a Java Developers Kit (JDK) or Java Runtime Environment (JRE) platform to be installed on your server's operating system. Please see the Java section of our Supported Platforms page for details on which versions of Java are supported.
For instructions on how to install a supported Java platform for iSymphony, please refer to Installing Java.
