hi, we have a 4 x node cucm 8.6 cluster, that was originally installed with no domain suffix and servers defined as ip address (phones register with cucm ip, no dns). We have a requirement for users to access ccmuser page using a trusted certificate, i understand this will require all nodes to have the domain suffix set on each node when using the cli command set network domain xxxxx.xxxxxx, this command does provide a rather scary warning regards replication and certificates, i was wondering if anyone has ran this command recently? I just want confirm that this will only impact intercluster traffic and that phones will still register via cucm ip (no phone dns required).
