Media services for unified communications expand to include support for Microsoft Lync 2013 to provide a fully integrated follow-me desktop and phone. Integration with Microsoft Lync 2013 gives users access to rich communication and collaboration features, such as presence and instant messaging, as well as interactive voice and video chat with support using PC over IP (PCoIP). Horizon View media services already support unified communications for Avaya, Mitel and Cisco.
