Platform support, APIs and application integration

[edit]

Because HCL Sametime is middleware, it supports application and business process integration. When within the context of real-time communications, this is often referred to[by whom?] as Communications Enabled Business Processes. Sametime integrates in either of two ways:

  1. by surfacing the application into an HCL Sametime plug-in
  2. by surfacing HCL Sametime capabilities into the target application

Some examples of integration between HCL Sametime and applications include:

  • HCL's products including HCL Notes, HCL Domino applications, HCL Connections, HCL Quickr
  • Microsoft office-productivity software including Microsoft Office, Microsoft Outlook, and Microsoft Sharepoint
  • portal applications, including portals built with IBM WebSphere Portal
  • web applications
  • packaged enterprise applications
  • embedded and client–server telephony applications

HCL Sametime Connect, the client component of HCL Sametime, is built on the Eclipse platform, allowing developers familiar with the framework to easily write plug-ins for HCL Sametime. It uses a proprietary protocol named Virtual Places, but also offers support for standard protocols, including Session Initiation Protocol (SIP), SIMPLE, T.120, XMPP, and H.323.

HCL Sametime Connect can run under Microsoft Windows, Linux, and macOS. Also available are a zero-download web client for Microsoft Internet Explorer, Mozilla Firefox and Apple Safari; mobile clients are also supported for Apple iPhone, Android, Microsoft Windows Mobile, RIM Blackberry, and Symbian. The HCL Sametime server runs on Microsoft Windows, IBM AIX, IBM i (formerly i5/OS), Linux and Solaris. Sametime can also be accessed using the free software Adium, Gaim, Pidgin, and Kopete clients.

History

[edit]

HCL Sametime became an IBM product in 1998 as the synthesis of technologies IBM acquired from two companies:

  1. an American company called Databeam provided the architecture to host T.120 dataconferencing (for web messaging) and H.323 Multi-Media Conferencing[4]
  2. Ubique, an Israeli company whose Virtual Places Chat software technology (also known as VPBuddy) provided the "presence awareness" functionality that allows people to detect which of their contacts are online and available for messaging or conferencing[5]

The Sametime v3.1 client was part of the standard platform loaded by the IBM Standard Software Installer (ISSI) for many years, enabling communications over the corporate intranet by hundreds of thousands of IBM employees. The next major release was the Sametime v7.5 client, built on the Eclipse (software) platform, enabling the use of the plug-in framework.[6]

In 2008 Gartner positioned IBM for the first time as a "leader" in Gartner's Unified Communications Magic Quadrant.[7]

These features facilitate real-time text-based communication within an enterprise environment, supporting seamless among colleagues. One-on-one chats allow direct, private exchanges, while group chats accommodate multiple participants for broader interactions. Persistent rooms maintain conversation threads indefinitely, allowing users to join at any time and access historical context without losing continuity. Presence awareness is a core component, displaying users' availability through visual indicators such as "available," "away," "in a meeting," or "do not disturb." These indicators update dynamically, including automatic transitions to "away" based on configured inactivity periods, helping members gauge responsiveness. Users can customize status messages to provide additional context, such as "At a doctor's appointment" alongside an "away" indicator, which clears upon status change. This system enhances communication efficiency by signaling when colleagues are best approached. Advanced messaging tools include read receipts, which notify senders when messages have been viewed, offering of delivery and engagement. Typing indicators alert participants to ongoing message composition, fostering natural conversation flow. Users can edit or delete sent messages, with options to undo deletions within a limited timeframe, ensuring flexibility in communication. Chat history is preserved with configurable time-to-live (TTL) settings, defaulting to 90 days for storage in the database, though administrators can adjust this minimum to 1 day via server configurations like CLI__ChatLogging__CL_MONGO_HISTORY_TTL. Maximum display limits for user-accessible history, such as 7 days, are also settable through parameters like CONVOMAP_MAX_DAYS. File attachments are supported in chats, with a default limit of 1 per file to manage server traffic, though this can be increased via policy configurations in files like policies.user.xml. Emoji reactions enable quick, non-verbal responses to messages, enhancing expressiveness without additional text. Cross-device synchronization ensures chat history persists across multiple logged-in devices, allowing users to pick up conversations seamlessly from desktops, mobiles, or web clients. Chats can briefly integrate video calls for escalation to richer interactions.

Recent Updates

In December 2023, HCL released version 12.0.2 of Sametime and Sametime Premium, introducing enhancements to server and client functionalities, including configurable time-to-live (TTL) settings for chat history storage in the database, with a default of 90 days that administrators can adjust to manage persistence. This version also improved persistence by ensuring user settings are maintained server-side across installations and devices. Additionally, it optimized deployments for environments, enabling single-server setups for scalable operations beyond Docker's limits, supporting up to larger user bases through Helm-based installations on Windows. In August 2024, HCL issued Fix Pack 1 (FP1) for version 12.0.2, focusing on UI modernizations to streamline user interfaces and incorporating bug fixes alongside security patches addressing multiple vulnerabilities in chat and meetings components. A subsequent FP2 in December 2024 extended these efforts with further fixes and introduced a non-containerized deployment option for chat-only environments on Windows, simplifying upgrades for legacy systems without requiring Docker or . Version 12.0.3, released in June 2025, built on these advancements with automatic transcripts for meeting recordings, enabling searchable content within reports to enhance post-meeting productivity. Deployment efficiency improved significantly, achieving approximately 50% faster installation times for Sametime Chat on Windows servers, reducing complexity for on-premises setups. Accessibility features were bolstered with compatibility, keyboard navigation, high-contrast modes, and accessible meeting controls, including AI-powered elements like real-time captions derived from transcripts. Ongoing minor releases and patches in have emphasized stability, with additional security updates for identified vulnerabilities and UI refinements. Looking ahead, HCL plans to expand non-containerized options further for legacy environments and integrate deeper AI capabilities, such as advanced for communication patterns, aligning with broader enterprise AI strategies.
