I have created many CSR request, ordered certs and installed them on both IIS/Windows and Apache/Linux. This is the first time I am ordering/installing an SSL cert for 3CX v14 use. First install of Version 14 Virtual PBX version. While installing 3CX, I get to the option where it ask me if I want to import a cert or generate a self signed cert. I do NOT want to use a self signed cert but I don't yet have one to import. I would like to order a cert but in order to do that I normally need a CSR. There is not option to create a CSR at install time so?? How should I create the CSR for 3CX use? If I use a self signed for now, can I change to the cert I purchase later or will I have to do the whole install over? Since we use Yealink phones, I will need to purchase a MUCH more expensive wild card cert from a more expensive Cert Authority because Yealink phones only allow by default a few Cert Authorities. Because this will be an expensive cert, I want to be sure I order it correctly and hopefully it can also be used for SIP TLS when I set that up later. I have read that the TLS cert needs to be a separate cert but, I am not sure about that right now, need to research further. Thanks in advance for any assistance with these issues.
