I currently have my CUCM 7x cluster sync'd with AD. I am currently syncing the telephoneNumber field for the Phone number. I need to change this to sync the ipPhone field instead. I have been told that to do this I need to create a new LDAP Directory integration and sync with that. Problem is that I am concerned that I will lose all of my user configuration (associated devices, profiles, etc.).
Has anyone done this?
As long as you do this and the user ID attribute you use is the same, AND you do all this before the garbage disposal runs you should be fine.
Any account that is not synched is marked as inactive and the garbage disposal runs at 3:15 AM, it might take up to 48 hours for the accounts to be removed from CUCM server.
Once you force a resync if the users are found in AD they will be marked as active again.
if this helps, please rate
