I have already setup our phone server, however our network infrastructure is changing. With that change we are getting new static IPs. I see at erp.3cx.com I can release the FQDN but not change the IP address. Also on the phone server I see we can change the Public IP address. Does changing the IP address on the phone server change it on the FQDN? We are currently running 3cx v15 on 2012 r2.
