Microsoft Dynamics CRM 4.0 Office Communication Server 2007 with Sanjay Jain

Hello,
Thanks but this demo is disapointing: the same person is a contact and a crm user. This was leading to lot of problems in CRM 3 because the email addresses were he same.
Could you tell us more about having a this king of situation: should we replicate internal users as contact to inclue them in marketing list ? Is it working now ?

Regards

Dear Sir,

Currently have these servers:
-Win2k3 Enterprise AD
-Win2k3R2Sp2 64bit Exchange 2007
-Win2k3 Enterprise OCS2007 (Office Communication Server)
-Win2k3 Enterprise CRM4+SQL2005+CRM Email Router

And these client
-WinXP1+Office Communicator 2007
-WinXP2+Office Communicator 2007

All pcs above in 1 subnet
send IM between Communicator 2007 is working

I am following this URL
http://channel9.msdn.com/ShowPost.aspx?PostID=375129
But I can't get presence appear in my CRM4 contact "Full Name" column
What I did was just tick "Enable presence on this column"

Questions:
-In my setting I separate OCS than CRM4 server. Do I need to install it in 1 server
-How CRM4 know where OCS server located.

thanks
