Federate with Your Trusted Partners: Administrators can enable federation with any other organization running Lync Server 2010 or previous versions including Office Communications Server and Live Communications Server.

Keep in Touch More Easily: Once enabled, users from one organization can add users at another to contact lists, send them instant messages, and see their presence information.

Experience Full Unified Communications Capabilities: Users can choose the best way to communicate for the task at hand—voice, video, and more—and can easily escalate person-to-person sessions to multi-person conferences.

Save Money: Federated communications use the Internet, not the public phone network—helping to reduce money spent on phone bills and third-party conferencing services.
