[cisco-voip] UCCX Install won't see Sub in CUCM Cluster

Mon Jun 7 10:45:31 EDT 2010

Unless I'm misunderstanding this is from the SRND.

There are some situations in which configuring and using DNS might be unavoidable. For example, if
Network Address Translation (NAT) is required for communications between the IP phones and
Unified CM in the IP Communications network, DNS is required to ensure proper mapping of NAT
translated addresses to network host devices.

What about the phone proxy deployment requires your infrastructure (ie servers, not the endpoints)  be configured to use DNS?

These are the same places with trading floors with billions of dollars using host files in Unix to ensure they work non-stop. Since DNS is maintained by the server team in the Enterprise your relying on someone else as well.
