hello,
I bought a domain name and an SSL certificate from NAMECHEAP.
I don't have a fixed public address and I want to install 3CX using the domain name I bought from NAMECHEAP
I don't know how to do it
Thank you for your help
From what I can see, I believe you have a Pro key, so you will have the option to use a Customer FQDN and your certificate.
kieferschild though is right, if you don't have a Static Public IP address, you will have to change manually update your own DNS records each time the Public IP of the PBX changes.
I think you should choose between the 2 options:
Talk to your ISP and change your Public IP to a Static one, then you can use your own Certificate/FQDN
or
Leave your Public IP as Dynamic and use a 3CX FQDN/Certificate, and leave 3CX to update your DNS records automatically whenever your IP changes.
