Warning: For security reasons, the document is displayed in restricted mode as it is not the current version. There may be differences and errors due to this.

iSymphony can run on a variety of hardware and software platforms. Please see the following pages for details on the requirements for each system:

Client Requirements

Since version 3.0, iSymphony is now a web application, accessed through a standard web browser. As a result, the software requirements have been greatly relaxed since version 2.

iSymphony uses some of the newest technologies available with browsers to provide you with the best experience. As a result, some older browsers may not support the features that iSymphony requires. Please see the browsers section of the supported platforms page for details on which browsers can be used to view iSymphony. 

Failed to execute the [error] macro. Cause: [The required content is missing.]. Click on this message for details.

We typically recommend that you use Chrome to access iSymphony, as our performance testing has indicated that Chrome provides the best experience with a Javascript-heavy application like iSymphony.

Server Software Requirements

iSymphony is a web based application that runs an embedded web server in order to provide client functionality within a user's browser.

Operating System

Please see the operating systems section of our Supported Platforms page for details on which operating systems can run iSymphony. 

If you are building a new phone system and are considering iSymphony in your plans, we recommend using the FreePBX distribution.

Java

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.

Server Hardware Requirements

iSymphony will run well on any reasonably fast computer (e.g. a modern 2.0+ Ghz dual core processor). Memory and CPU requirements depend mainly on the amount of activity and users that your installation will have, as well as the maximum number of concurrent requests that the system will experience during peak hours.

  • iSymphony currently requires a physical system or Virtual Private Server (Such as OpenVZ, KVM, VMWare or similar) with a Network Interface Card (NIC) that supports MAC address assignment.
  • A small system that needs to handle around 5-10 concurrent users and around 200 calls per day would work sufficiently on a modern system with a 2.0+ GHz dual core CPU and 2 GB of available RAM.
  • A medium size system that needs to handle around 20-50 concurrent users and around 500 calls per day would work sufficiently on a modern system with a 3.0+ GHz dual core CPU and 2 GB of available RAM.
  • A large system that needs to handle around 50-100 concurrent users and around 1000 calls per day would work sufficiently on a modern system with a 3.0+ GHz quad core CPU and 3 GB of available RAM.
  • Utilizing a lower end CPU, like an Intel Atom, can handle a small amount of concurrent users (~5) and around 100 calls per day, but is not recommended.
  • iSymphony was built from the ground up to take advantage of multi-core CPUs. Running iSymphony on systems with only one core available is not recommended.

 

Please note that performance heavily depends on your dimensions and your usage pattern, much more than what is simply covered here. 

We would appreciate it if you let us know what hardware configuration works for you. Please create a ticket in our support system with your hardware specification and mention the number of users and issues in your iSymphony installation.
