It does not support integration but you can configure directory access with CUCME.
By integration I mean creating CUCME users by syncing with LDAP.
By directory access I mean the ability to search LDAP user records from an IP phone by name and dial associated phone numbers.
You can do this using the CallManager SDK as described in the link below.
You can try http://www.visualviewmail.com this is a new AD directory but it integrates nicely with CUCME and Exchange 2010.
