In this article, we focus on how to configure the FQDN and link an SSL certificate for secure protocols in version 20 and above of 3CX.

What is an FQDN and why is it important?

FQDN, or “Fully Qualified Domain Name,” is the complete domain name that identifies a specific location on the internet. In 3CX, the FQDN is used to define the location of your server on the network, making it easy for users and clients to reach it.

The importance of using an FQDN in 3CX

  • Makes the system reachable from anywhere in the world.
  • Improves system security by defining trusted domains.
  • Delivers a smooth user experience through easy-to-remember domain names.

  1. Log in to the 3CX management console.
  2. Go to the “Settings” section, then “Network.”
  3. Enter your FQDN in the designated field.
  4. Save the changes and restart the system to apply the new settings.

What is SSL and why is it necessary?

SSL, or “Secure Sockets Layer,” is a security protocol that encrypts the data exchanged between the server and the user. In 3CX, SSL is used to secure communications and protect sensitive data from breaches.

The benefits of using SSL in 3CX

  • Encrypts the data exchanged between users and the server.
  • Protects sensitive information such as passwords and personal data.
