I just upgraded a customer from 12 to version 14 SP2. During install I chose the separate local and external FQDN. I need to change the local FQDN in 3CX, then re-provision 3CX Clients. How can I do this? I searched Trouble Shooting >> Parameters for the internal FQDN and found a bunch of entries, do I just change them in there and I am good? I will also need to change the external FQDN once I get a second external IP address setup for this customer but that is secondary at the moment, the internal not being correct has broken their 3CX Client app completely. Thanks..
