Call Manager 9.1 Active Directory Question(s)

[allenratcliff]

Hello All!

Firstly let me establish that I am not an administrator of our VoIP system however I do manage the Server side of our network.  We are in the process of planning an Active Directory upgrade and I'm having some difficulty getting a question answered about the requirements for  Call Manager.  We are at version 9.1 of Call Manager currently with our Active Directory version at 2003 R2.  We are planning to upgrade to Active Directory version 2008 R2 (functional level) however we would like to use Server 2012 R2 as the OS for our AD servers.  From a Microsoft standpoint this is a valid solution, it's built into Active Directory that you can run at different "functional levels" of AD on higher server operating systems.  Any Call Manager applications that require a Windows operating system would run on whatever works for that (2003 or 2008 etc).  Can we use Server 2012 R2 as the Domain Controller operating system while running at 2008 R2 functional level for Active Directory and still retain our Cisco support?

Hi Allen,

This is from Cisco site (you already may have seen this), though it talk about the directory services but it is specifically mentioned 2008. 2012 may work and specially as you are saying with functional level set to 2008 shouldn't have any issues. But Cisco have not tested that and you may get into support issues (if any).

Its completely tested and supported with CUCM 10.X

Version 9:

Configure LDAP directory

If you want to do so, you can add users from your corporate directory to the Cisco Unified Communications Manager database by synchronizing the user data to the database. Cisco Unified Communications Manager allows synchronization from the following directories to the database:

• Microsoft Active Directory 2000
• Microsoft Active Directory 2003
• Microsoft Active Directory 2008
• Microsoft Active Directory Application Mode 2003
• Microsoft Lightweight Directory Services 2008
• iPlanet Directory Server 5.1
• Sun ONE Directory Server 5.2
• Sun ONE Directory Server 6.x
• OpenLDAP 2.3.39
• OpenLDAP 2.4

Thanks Terry!  We've asked the question and gotten a similar answer, I was hoping for something that reflected the difference between the OS and the AD functional level.  To be safe we'll stay at 2008 R2 on the OS and AD.
