Partitioned Intradomain Federation
More and more enterprises are choosing Cisco Unified Communications Manager IM and Presence Service as their IM and availability platform. These enterprises already have Microsoft Lync or Microsoft Office Communications Server (OCS) deployed and want to move their users over to an IM and Presence Service supported client.
During this transition, it is important that these users who migrate to an IM and Presence Service supported client can continue to share availability and instant messages with those users who are still using the Microsoft servers. For more information about supported IM and Presence Service clients, see the "Software Requirements" section.
Partitioned intradomain federation enables IM and Presence Service client users and Microsoft Lync or Microsoft Office Communicator users within the same enterprise to exchange presence Availability and IM.
This integration allows both IM and Presence Service and the Microsoft server to host a common domain or set of domains. Each user within those domains is enabled on either IM and Presence Service or the Microsoft server.

Partitioned intradomain federation requires that a user is enabled on one system only. This integration does not support a user that is enabled on both IM and Presence Service and the Microsoft server at the same time. |
IM and Presence Service uses the standard Session Initiation Protocol (SIP RFC 3261) to provide partitioned intradomain federation support for the following Microsoft server platforms:
-
Microsoft Skype for Business Server 2015, Standard Edition and Enterprise Edition
-
Microsoft Lync Server 2013, Standard Edition and Enterprise Edition
-
Microsoft Lync Server 2010, Standard Edition and Enterprise Edition
-
Microsoft Office Communications Server 2007 R2 Standard Edition and Enterprise Edition

The term Microsoft server is used in this document to refer to all supported Skype for Business, Lync and OCS platform types. Any information that is specific to a certain platform is identified. |
Partitioned Federation Deployment Overview
The following figure shows a high-level sample deployment of IM and Presence Service and Microsoft OCS within the same domain. This example shows an OCS deployment, but it also applies to the other supported Microsoft servers.
Both single presence domain and multiple presence domain deployments are supported. For multiple presence domain deployments, you must configure identical presence domains on both systems.

Single Domain Example
In this example, users within the presence domain called synergy.com on both theIM and Presence Service node and the Microsoft Lync server are able to exchange Availability and IM using partitioned intradomain federation because the synergy.com presence domain is configured on both systems. The common active directory enables contact searches and display name resolution for all users on both systems.

![]() Note |
Presence domains must be identical. For example, user1@abc.synergy.com cannot share IM and Availability with any of the federated users configured for intradomain federation on synergy.com. Move user1 from the abc.synergy.com presence domain to the synergy.com domain to enable user1 to participate in Partitioned Intradomain Federation in this example. |
Multiple Domain Example
In this example, users within the presence domains called synergy.com and synergy.co.uk on both theIM and Presence Service node and the Microsoft Lync server are able to exchange Availability and IM using Intradomain Federation because those domains are configured on both systems. The common active directory enables contact searches and display presence name resolution for all users on both systems. See the following figure.

Multiple Domain Misconfiguration Example
In this example, users on the domains called synergy.com and synergy.co.uk are properly configured for partitioned intradomain federation and can exchange IM and Availability. However, users within the domain called synergy.online.com on the Lync server are unable to exchange Availability and IM with users in the federated IM and Presence Service system because the synergy.online.com domain is not configured on the IM and Presence Service node. See the following figure.

To enable synergy.online.com users to exchange Availability and IM with users in the federated IM and Presence Service system, add a domain called synergy.online.com to the IM and Presence Service node.

You can configure additional presence domains on the IM and Presence Service system even if no users are initially assigned to those domains. |
