UCM - LDAP query

How does UCM behave when more than 1,000 results are returned from an LDAP query when binding to Active Directory?  I would bet that UCM supports RFC2696, LDAP Control Extension for Simple Paged Results Manipulation, but can someone able to verify this?

Re: UCM - LDAP query

Im almost positive, but the LDAP directory or OU you point CUCM to will sync the entire directory to its local informix database. When someone presses the Corp Directory button on phone, it is NOT making an LDAP call to whats programmed at CUCM.   To speed up the process, CUCM will sync all LDAP contacts based on First Name, Last Name and CN name (username).  If those objects in LDAP, it will keep a local copy for itself.  It will then sync upon certain times of the day typically once a day or when specified, but no shorter than 6 hour time frames.
