CONFIGURING YOUR 3CX
Step by Step Guide
You are now all set on the Mission Control Portal side and are ready to configure your Telnyx trunk within your 3CX system.
During the installation process, 3CX will ask you to specify a username and password which will be used to login to the web interface. 3CX automatically detect your pubic IP address. You can then specify if this is a static or dynamic IP. You can configure your 3CX with an FQDN and 3CX will provide you with one - they do this to ensure your FQDN is set to resolve to your Public IP and for generating certificates. You'll then choose your default network adapter and decide whether you want the extensions to use the local IP of your PBX or the FQDn you created. At the end, you'll choose your preferred http/https port numbers which will be used to allow you to access the 3CX web interface via your FQDN or Public IP.
Great you can now login and begin your configuration!
