General notes

Last Updated: 14.06.2019 - Notes: Information on Intel Processors and CPU family specifications is available here: http://www.intel.com/content/www/us/en/homepage.html. Recording and Voicemail - every 60 seconds of recorded audio consumes approximately 1MB. Take this into consideration when choosing hard disk size.

Logging - Verbose logging consumes disk space. On a busy system the logs folder can consume up to 1GB per day.

 

Every 5000 calls in full verbosity consume 2GB of HDD space. This list describes the recommended operating systems. For a list of supported operating systems click this link: https://www.3cx.com/docs/supported-operating-systems
