Those capabilities include presence information, enterprise instant messaging, web conferencing, community collaboration, and telephony capabilities and integration. It is sold by the Lotus Software division of IBM. Because IBM Sametime is middleware, it supports enterprise software and business process integration (Communication Enabled Business Process), either through an IBM Sametime plugin or by surfacing IBM Sametime capabilities through third-party applications. IBM Sametime integrates with a wide variety of software, including Lotus collaboration products, Microsoft Office productivity software, and portal and Web applications. ==Features== IBM Sametime is a client–server enterprise application that includes the IBM Sametime Connect client for end-users and the IBM Sametime Server for control and administration.
