3cx installation on Debian

[Saniel]

Hello,
I want install 3cx on Debian 8 with my own FQDN, but on FQDN Configure step i just can't choose this parameter in both of installations (web and console). DNS are already configured and Lets Enrypt process completed. Maybe someone encountered with this problem and can share the solution.
Thanks.

Hi there,
If you have used your key with a different FQDN in the past then you need to release it before you can choose a different FQDN. Also PBX edition keys do not give you the option to use your own FQDN.

Ok, thanks.

OK, could you tell how can I use generated LE SSL certificate for the TLS connection on port 5061?

in case you are using the 'PBX Edition' as key then this is to be expected as this only allows to use the 3CX managed external FQDN. See here for more info: http://www.3cx.com/phone-system/edition-comparison/
