IntroductionIntroductionIntroductionIntroduction

• This document describes feature interoperability and documents the steps and configurations necessary for Cisco Unified Communications Manager Express (CUCME) to interoperate with Microsoft Office Communications Server (OCS) 2007 R2 Enterprise Edition. These features include Microsoft Office Communicator (OC) features, Desktop (DTP) or IP Phone features, CUCME administration, configuration and provisioning. It aims to provide a good understanding of what works and what does not work in terms of the feature interaction between various components of the CUCME, and OCS. It also provides guidance to deployment participants of the limitations, expected behaviors as well as known issues. Please note that this document does not address performance and scalability, which are part of broader criteria for a deployment-ready solution

• As shown in the Network Topology diagram, interoperability testing was performed between the CUCME and the OCS 2007 R2 using a single OCS 2007 R2 pool. Please note the absence of a CSS11501 Load Balancer. This hardware component is not required for OCS 2007 R2 Enterprise Edition deployments with only one Front End Server per pool. Multiple Front End Servers installed for performance or redundancy, per pool, will still require a load balancer.

LimitationsLimitationsLimitationsLimitations

• The default normalization rule for the OCS is to have the “+” sign as a prefix to the phone DN. However, as of the current release, the CUCME does not support and recognize this. Thus, when “+” is used as prefix to the DNs, call control over the phones is lost even though the MOCs are registered. Instead of making calls using user names among registered MOCs, MOC to MOC calls were made by entering the DN manually on the MOC. The number entered becomes one of the contact selections.

• Due to the normalization rule requirements stated above, the Reverse Number Lookup feature is only supported on “Communicator Calls” or MOC to MOC calls. For calls using the manually entered DN, the calling name is not displayed in the “Accept Call” dialog box because DNs without the prefix “+” is not recognized by the OCS.

• OCS 2007 R2 does not support call conferencing through remote call control. Conferencing is available in IP Phone only or OC only call scenarios.

• Call forward setting made on the Cisco IP phone (desktop), using its soft key button or the Cisco UCM phone configuration page is not reflected by the Microsoft OC GUI. As of Microsoft OCS 2007 release, this feature is not supported. The Microsoft OC can override any call forward setting manually configured on the IP Phone and vice versa.

• Do Not Disturb (DND) is an unsupported feature with respect to CUCME integration. Thus, any OC client with DND feature enabled will still have any received calls routed to its controlled IP Phone and the “Accept Call” dialog box will still appear on the associated MOC.

• Refer to the Features section below for a list of supported and unsupported features in this integration.

This screen shot shows the DNS entries. This highlights OCS Pool 1 in MSPBX.com domain



This screen shot shows the DNS entry for the CUCME connected to OCS in a different domain. The CUCME is in domain cme.com



Reverse Lookup Zone

This screen shot shows PTR record entry for CUCME for reverse lookup



This screen shot shows PTR record entries for OCS Pool1 for reverse lookup. The PTR record highlighted was used for OCS-CME integration.



Front End Server Configuration

Pool Properties

This screen shot shows the General Settings for OCS Pool1 where it highlights static route to CUCME.

Static route to CUCME added in OCS Front End server.



This screen shot shows the Voice Settings for OCS Pool1 where it highlights the normalization rule associated with the Location Profile for the OCS environment. Please refer to Microsoft documentations for more details.



This screen shot shows OCS Pool1 Front End server settings. Configuration details are found in the following pages.



This screen shot shows how to add/edit Front End properties by right clicking on applicable pool.



Click on Add to add and configure Front End IP address, port and transport protocol



This screen shot shows how to add/edit pool properties by right clicking on applicable pool.



Configuration here made using the Wizard during install



Add CUCME FQDN in the ROUTING tab



Make sure to check these boxes

Add and enable CME Host Authorization using HOST AUTHORZATION tab



Active Directory User Configuration

This screen shot shows how to add or configure a new user which is done in the Active Directory. This is done by right clicking on USERS. Users added here will be displayed in the pool.

This window pops up when initializing NEW user configuration. Populate the user name and logon information.



Make sure to check these boxes

This window pops up after clicking on NEXT > in the previous page.

Select a Password for user login and enter it here



Complete the USER configuration from the Active Directory.

This window pops up when right clicking on a user list from the previous page.

Click to complete user configuration



This screen shot shows how to enable Remote Call Control (RCC)

Enable Remote call control. Enter the FQDN of the CUCME in the Server URI section. All RCC clients MUST have the same configuration for the Domain name. Obviously, different users ID’s.

Notice this number is not prefixed with “+”. CUCME current release does not support and recognize “+” sign.



Microsoft Office Communicator Configuration

Click here to configure logon options



Fill in the user account name and then click Advanced to enter the corresponding pool name.



Click on Manual Configuration to configure connection settings if not already setup in the DNS



This is a typical screen appearance upon logon by a user. Contacts can be entered here.
