A+ for 3CX Security

3CX v18 brings additional security updates and enhancements and focuses on remote worker reliability.


3CX Security Updates:

  • Latest version of Debian Linux 10 
  • Latest Libraries & Technologies
  • Latest Nginx, OpenSSL support
  • Latest Ciphers for TLS
  • Out-of-the-box, easy config SRTP support
  • A+ Security Status (SSL Labs) & Immunilabs A status

  • Latest PUSH in server & web clients

  • Calls are no longer disconnected when network changes or drops
  • Removed unnecessary SIP mappings
  • Saves local ports & CPU processing
  • 50%+ reduction on memory & processor usage


Codec Management Improvements:

  • Enhanced Default Codecs for Apps & Webclient
    • Wifi- Apps use G711
    • Mobile Data Network- Apps use G729
  • Ability to set system wide default codec for apps


Voice Engine Improvements:

  • Latest SIP Library for compatibility & security
  • Easy to configure SRTP
  • IPv6 Support for Apps & Console


More Privacy with 3CX Video Conferencing:

  • Video meeting data will no longer be synchronized to the 3CX Cloud service in order to facilitate meetings.
  • Meetings now run under the same FQDN as the customers; Web Clients or Management Console so meeting data is now stored on the client’s 3CX.
    • This reduces 3CX privacy policy in regards to 3CX Video Conferencing by 60%.
  • Currently, 3CX provides only autonomous media processing/conversion units in the cloud that connect video streams together.  In the near future, 3CX plans to provide the client with the means to control those themselves and give them full control over their meetings (and the need to write your own privacy policy).
