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.
