Once you have installed 3CX and have access to the Linux console, you can download the Relay setup program directly to your Linux server. There are essentially 3 steps to install the Relay:

1. Download the setup program with the following command

sudo wget https://installers.voiptools.com/Downloads/18.0/3CXRELAY/LINUX/setup8

When the installation is complete, the setup program will display a message with the URL needed to access the web-based Relay administration console. Your URL should be something similar to the following:

http://<3cx-server-ip>:8800

  Replace <3cx-server-ip> with the IP address of your 3CX server, or FQDN.
