[cisco-voip] New Deployment - AD not ready so?

[Voll, Scott]

Darren-

 

I just got into Cisco IPT last year with a ICS 7750 running CM 3.3.4,
Unity 4.0.2 and then bought a 7825 and IPCC Express 3.1.2.  We are in
the process of migrating off the ICS to 7835's. 

 

Just a head's up on integration with AD.  We integrated with AD 2000 and
just know if you make a lot of AD changes, expect things to break in
your IPT network.  When AD and IPT work, everything is great, but as
soon as your SysAdmin changes your AD policy, kiss your IPT good bye.
I've spent many mornings on the phone with TAC to find out the night
before someone screwed with AD.

 

With all that said.  CM and IPCC is a simple plug-in to integrate with
AD.  Make sure you keep them in there own workgroup.  Unity you can
install with Exchange 5.5 and then upgrade to 2003.  AD Prep is required
to get this working.  Exchange 2003 needs to run on a Win2k3 box but you
can run in AD2k mixed mode.

 

My suggestion, use the CM directory and forget AD. But if you want the
AD integration, I believe you can run the AD plugin at any time down the
road.  And if you can, wait to install Unity until you have an Exchange
2k3 box.  It will just make your life a whole lot easier.  Can you get
the Exchange 2k3 box up and as you bring people onto IPT migrate there
mail box store?  How are you implementing IPT?  Department by
department, or all at once?  Do you control the AD domain and the IPT
network?  Or someone else is in charge of the AD network?

Hi All,

 

We're about to deploy the core of a new IP Telephony network using CCM
4, Unity 4 and IPCC Express Standard 3.5

 

Unfortunately Active Directory has only been deployed for server
registrations and users are still in the old NTLM based NT4 domain with
full trust priveleges between the two and the users are still using
Exchange 5.5, but we'll be moving them to AD on 2003 and Exchange 2003
over the next 12 months. 

 

This does mean that the CCM, IPCCE and Unity servers can be on the new
AD domain and I'm thinking this is the best thing to do since Unity
especially wants to modify the tree to add the Cisco subtree for service
location etc

 

Unity storage is another issue, I'm thinking maybe it's best to use
local storage for VM and use Exchange 2003 later but can't find any
information on how to migrate this way or if I use Exchange 5.5 then
upgrade to 2003 what will be the impact on Unity? And it's AD prep
requirements?

 

User authentication/LDAP is the other issue as I think we'd have to use
the internal CCM4 directory with external authentication and then
migrate to use Active Directory later but I'm not sure if this is
advisable or what the best option is.

 

What would people recommend for this type of deployment?

 

Darren
