All,</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=531042011-14092004>We're about to
deploy the core of a new IP Telephony network using CCM 4, Unity 4 and IPCC
Express Standard 3.5</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=531042011-14092004>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. </SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=531042011-14092004>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</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=531042011-14092004>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?</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=531042011-14092004>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.</SPAN></FONT></DIV>

recommend for this type of deployment?</SPAN></FONT></DIV>
