CUP MOC call control OCS change

[AskQ2Forum_2]

            We have cup 7.08 , cucm 7.x .

CUP is integrated to custers OCS servers to provide call control. Customer is changing their OCS servers to OCS R2 (new servers) , they are also changing domain the OCS servers sit in.

Would I be correct to assume that all we have to do is update the existing incoming access control lists for the new servers and also update our dns server's to resolve to the new domain - please advise, any other changes.?? 

The proxy domain is currently not set anyway so hopefully won't need to touch that. Customer will require both OCS servers to be working in tandem for migration , i.e OCS 2007 and OCS 2007 R2 ..... Regards  Jaginder

RCC or Remote call control needs a bit more configuration on OCS side and CUPS side. Please follow the doc here -

http://docwiki.cisco.com/wiki/Cisco_Unified_Presence,_Release_7.x_--_Configuring_Cisco_Unified_Presence_Release_7.x_with_Microsoft_OCS_for_Remote_Call_Control

Please skip the security part if TLS is not desired.

Following three sections are necessary -

• How to Configure Cisco Unified Communications Manager for Integration with Microsoft OCS for Remote Call Control
• How to Configure Cisco Unified Presence for Integration with Microsoft OCS
• How To Configure the Deskphone Control Settings

Hope it helps!
