微软下一代开发平台前瞻：Unified communications

      微软正在尝试引起开发者的更多兴趣，他们在开发平台产品线中添加了一个名为 unified communications 的平台结构。

      Unified communications 主要基于 Exchange Server 与 Office Communictions Server (OCS)构建，微软打算将其打造为一个 UC 平台，围绕 PBX 系统，桌面电话，VoIP 平台，Web 会议，传真和移动电话相结合的办公室统一通信标准，这意味着微软的一款软件就可以控制你一天中所需要用到的所有通讯工具。这一开发平台预计包含如下 API，请开发人员予以关注。

• Office Communicator Automation API, allowing developers to “query for presence information, launch IM, voice and video sessions, and enhance the client experience”
• Communicator Web Access, an Ajax API for creating Web clients similar to the Web-based Office Communicator
• OCS Server API for building plug-ins to OCS that can “monitor, archive and affect the routing of messages through the server”
• Unified Communications Client API (UCCA) for creating SIP (Session Initiation Protocol) clients
• Unified Communications Managed API (UCMA), codenamed “Warsaw,” for creating SIP clients, SIP servers and middle-tier applications
• Speech Server API for creating speech/telephony applications.
