Avistar Communications Corporation announced at Citrix Synergy(TM) 2012 (Booth # 607) that it is demonstrating the Avistar C3 Conference(TM) solution capable of delivering continuous presence multiparty videoconferencing, interoperability and virtualization features to Microsoft Lync users. The Avistar C3 Conference(TM) solution is designed to expand the capabilities of the Microsoft Lync unified communications (UC) platform, while enabling clients and partners to enhance their UC features within a virtualized server environment, such as Citrix XenServer(R). As the solution is based entirely on an all-software design, it can be deployed using standards-based hardware, on premises or within a cloud environment. Additionally, the Avistar solution supports both room-based H.264 and Microsoft Lync-based RT media streams. This is important as the Avistar C3 Conference solution enables clients and partners to design a scalable and economical interoperability strategy between their conference room video solutions and their RT endpoints. This is achieved by seamlessly and simultaneously processing media streams between H.264 and RT endpoints. In addition to these processing capabilities, the Avistar solution enhances the Lync user experience by providing continuous presence multiparty layouts within the client itself.
