Failed to contact the iSymphony server

A few things to note:

  1. Disabling REST in FreePBX should not effect the REST communication between the iSymphony V3 FreePBX module and the the iSymphony V3 server as it utilizes its own rest library separate from FreePBX.

  2. The iSymphony FreePBX module version (reported in Admin->Module Admin) is different than the iSymphony Server version (reported in Admin->iSymphony/iSymphony V3).

  3. There are two iSymphony modules in the FreePBX repository for iSymphony one for Version 2 and one for Version 3. The module for version 3 has a version number of 3.0.0 and above.

  4. The Open JDK is not supported by the iSymphony V3 Server. http://docs.getisymphony.com/display/ISYMDOCS/Supported+Platforms

I does sound like there is a communication issue between the iSymphony FreePBX module and the iSymphony Server. I would need to see the following two logs to determine what the communication issue is:

/var/www/html/admin/modules/cxpanel/main.log
/var/www/html/admin/modules/cxpanel/error.log
