3CX Video Conference: Better Privacy & Performance with V18

By:  Leonidas Georgiou, 3CX Product Manager 

With the release of the Version 18 update 1, 3CX Video Conference sets a new standard for privacy and performance. Now running on your company’s own installation, to safeguard both your data and customer data.

Improved Performance By 60%

We’ve completely rewritten the web app which now performs up to 60% more resource-efficiently than the previous versions. This allows a higher frame rate for a smoother video rendering and is less demanding on older hardware.

Retaining Privacy & Reliability

Since Video Conferencing now runs in your own installation, meetings no longer need to share attendee information to 3CX to create the invite or for attendees to join a session.

To work reliably, the 3CX System and the cloud provided media distribution units (MCU) need to establish a link for the duration of the meeting. This is required to mitigate potential issues caused by unstable or unreliable WAN access to the 3CX System (e.g., attendees being denied access to meetings or meeting reports being issued before the meeting ends). V18 Update 1 has several changes to this area including a more sophisticated method to re-send meeting recordings to 3CX reducing the need for connectivity to the meeting.

HTTPS Port Configuration

To ensure your audience can access your meetings it is strongly recommended to run 3CX off the default HTTPS port 443. This will secure higher access probability for strictly configured networks such as enterprise, hotel, and airport internet access. In case you have already used port 443 on your WAN IP address and you don’t have an additional IP to run 3CX from on-premises, you could consider relocating 3CX into the cloud.


Lastly, the client now shows the connectivity status of the meeting. This allows IT administrators to monitor the dial-in status of the 3CX System to the meeting and how reliable the link of your 3CX to a meeting is in general. This is beneficial as it will equip the admin team to review the WAN connectivity if required.
