our customer will raise the functional level to their domail to windows server 2008 R2 and we have an integration between CUCM 7.1.3 with LDAP directory So is windows server 2008 R2 is supportted with the call manager version 7.1.3 the documents does mention anything about 2008 R2 only AD windows server 2008
AD 2008 R2 might work as R1 & R2 doesnt make much difference from CUCM perspective but it's not tested with any of the released CUCM as of date. Testing is under progress with CUCM 9.0.
