HCL Sametime Premium (formerly IBM Sametime and IBM Lotus Sametime) is a client–server application and middleware platform that provides real-time, unified communications and collaboration for enterprises. Those capabilities include presence information, enterprise instant messaging, web conferencing, community collaboration, and telephony capabilities and integration. Currently it is developed and sold by HCL Software, a division of Indian company HCL Technologies, until 2019 by the Lotus Software division of IBM. Because HCL Sametime is middleware, it supports enterprise software and business process integration (Communication Enabled Business Process), either through an HCL Sametime plugin or by surfacing HCL Sametime capabilities through third-party applications. HCL Sametime integrates with a wide variety of software, including Lotus collaboration products, Microsoft Office productivity software, and portal and Web applications.
