i know that is better specify an IP address for all member of CUCM cluster. The procedure deals with going to CUCM servers, change the name to IP and, finally, change the URL's in "enterprise parameters" to allow phones use IP too. My question is which configuration steps are better between this 2:
A. Configure all cluster members by name and, after the last subscriber is added, change the names to IP of all members (and change "enterprise parameters" URL's)
B. Install the Publisher, change his name to IP, add the following Subscribers using IP directly.
