I read 3CX in Cooperation with Certificate Authority Let’s Encrypt, in which it says I have combed the Version 15.5 Administration Manual (which can't be searched :-(( ) and can't find anything on this. I did click on the "For more information click here" in the admin UI Security Settings, Secure SIP tab, and got to How to Configure Secure SIP – TLS but that shows how to use SimpleCA to create a bogus cert. I am interested in using Let's Encrypt. Where is the "streamlined process" info? Did I miss it during the PBX Express process maybe? Is it available after the fact (I used PBX Express on Google Cloud). I am a 3CX Professional licensee.
