When using 3CX with Cassini, you may encounter situations where the Web Interface or the Web Service stops running and you have to restart the 3CX services to get it running again, or where the 3CX Webserver service fails to start. To be able to resolve this issue you need to do the following

  • Go to Start / Run and type %allusersprofile%
  • Locate a folder named "Ultidev", open this folder and find the folder named "Cassini".
  • Inside the "Cassini" folder you will see an .xml file named "CassiniMetabase.xml".  Delete this file.
  • Download the attached file below and place it in this location.
Note: The physical path tag must be changed to the path that matches the location of the Http folder on your 3CX PBX Machine.
The below extract gives an example of a PBX installed in the default location on a Server 2012 / Windows 7/8 operating systems.

  • Go to "Services.msc" and start the "Ultidev Cassini Web server".
  • Confirm that the service is started and that it remains started. (Press F5 to confirm that it remains started. If after 1 minute it is still started, then the issue is fixed)
  • Also check event viewer / application for any events posted by Cassini.
This concludes one of the most common issues regarding Cassini service that fails to work properly.
